The -OH from the sodium hydroxide is a nucleophile, and will attack the carbon bonded to the chlorine. Because the chlorine is on a secondary carbon and the base -OH is not large enough to cause steric hinderanceboth substitution and elimination will occur. The exact ratio of the two reactions will depend on other factors like the temperature and the solvent used.

When organic compounds are oxidized in the body, energy and what other 2 major products are formed?

Sign up!When an asymmetrical reactant such as HBr, HCl and H 2 O is added to an asymmetrical alkene, two possible products can be formed. Markovnikov Rule, which states that hydrogen will be added to the carbon with more hydrogen, can be used to predict the major product of this reaction.

We notice that the alkene is asymmetrical as carbon-1 and carbon-2 are bonded to different groups. Therefore if we add HBr to this alkene, 2 possible products can be formed. Carbon-1 is bonded to 2 hydrogen, while carbon-2 is bonded to 1 hydrogen only. Hence according to Markovnikov Rule, when hydrogen is added to the carbon with more hydrogen, we will get the major product.

This means that when hydrogen is added to carbon-1, which has more hydrogen, and bromine is added to carbon-2, the product 2-bromopropane will be the major product. Conversely when hydrogen is added to carbon-2, which has less hydrogen, and bromine is added to carbon-1, the product 1-bromopropane will be the minor product. Let's explain Markovnikov Rule by discussing the electrophilic addition mechanism of alkene with HBr.

In the first step, electron rich alkene will attack hydrogen of HBr which is partial positive charge.

24.5 Common Classes of Organic Compounds

Two possible intermediates can be formed as the alkene is asymmetrical. For the structure on the left: when hydrogen is added to carbon-1 with more hydrogen, the carbocation intermediate on carbon-2 formed is bonded to 2 electron donating alkyl groups.

More electron donating groups will stabilise the carbocation to a greater extent. Hence it is more stable, more likely formed and eventually becomes the major product.

For the structure on the right: when hydrogen is added to carbon-2 with less hydrogen, the carbocation intermediate on carbon-1 formed is bonded to only 1 electron donating alkyl group. Less electron donating groups will stabilise the carbocation to a smaller extent. Hence it is less stable, less likely formed and becomes the minor product.

My weekly classes in Singapore are ideal for students who prefer a more structured program. Online lessons are also available!No, the molecule is not chiral since it is superimposable with its mirror image. Take particular care to indicate three-dimensional stereochemical detail properly. Take particular care to indicate stereochemistry properly. Label the chiral centers as R or S. Assign each chiral center as having either R or S configuration. This is not a racemic mixture but a mixture of diastereomers.

The specific rotations of diastereomers are not the same in magnitude nor necessarily opposite in sign. Explain briefly. The results of his measurements are shown below. Given that the sample cell had a path length of If a solution of 2. If the mixture has a concentration of 2. What is the specific rotation of a solution containing 7. Note: Some H atoms are omitted for clarity. They could not be isolated because they are actually the same molecule.

The presence of asymmetric carbons is not required for a molecule to be chiral. The only requirement is that the molecule be nonsuperimposable with its mirror image. Structural features other than asymmetric carbons can lead to chirality. How many stereoisomers exist for this structure? The molecules are related as diastereomers and hence have different boiling points. Another method involves the chromatographic separation using a chiral stationary phase. Enantiomers will be retained differently by the chiral stationary phase of the column.Unlike halogens, hydrogen halides are polarized molecules, which easily form ions.

Hydrogen halides also add to alkenes by electrophilic addition. The addition of hydrogen halides to asymmetrically substituted alkenes leads to two products. This arrangement creates a more stable carbocation intermediate. Hydrohalogenation mechanisms. The first step in the addition of a hydrogen halide to an alkene is the dissociation of the hydrogen halide. In asymmetrically substituted alkenes, two different carbocations are possible. The major product is generated from the more stable carbocation, while the minor product forms from the less stable one.

The mechanism for this reaction starts with the generation of a bromine free radical by the reaction of hydrogen bromide with peroxide. The bromine free radical adds to the alkene, forming a more stable carbon free radical.

The major product then forms from the intermediates by reacting with hydrogen bromide. Previous Alkenes Halogenation. Next Alkenes Oxidation and Cleavage Reactions.

Alkenes: Hydrohalogenation. Adam Bede has been added to your Reading List!The general properties and reactivity of each class of organic compounds is largely determined by its functional groups. In this section, we describe the relationships between structure, physical properties, and reactivity for the major classes of organic compounds. We also show you how to apply these relationships to understand some common reactions that chemists use to synthesize organic compounds.

The boiling points of alkanes increase smoothly with increasing molecular mass. In contrast, the melting points of alkanes, alkenes, and alkynes with similar molecular masses show a much wider variation because the melting point strongly depends on how the molecules stack in the solid state.

It is therefore sensitive to relatively small differences in structure, such as the location of a double bond and whether the molecule is cis or trans.

Because alkanes contain only C—C and C—H bonds, which are strong and not very polar the electronegativities of C and H are similarthey are not easily attacked by nucleophiles or electrophiles. Consequently, their reactivity is limited, and often their reactions occur only under extreme conditions. For example, catalytic cracking can be used to convert straight-chain alkanes to highly branched alkanes, which are better fuels for internal combustion engines.

The result is a mixture of radicals derived from essentially random cleavage of the various C—C bonds in the chain. Pyrolysis of n-pentane, for example, is nonspecific and can produce these four radicals:. Recombination of these radicals a termination step can produce ethane, propane, butane, n-pentane, n-hexane, n-heptane, and n-octane.

Radicals that are formed in the middle of a chain by cleaving a C—H bond tend to produce branched hydrocarbons. In catalytic cracking, lighter alkanes are removed from the mixture by distillation.

Radicals are also produced during the combustion of alkanes, with CO 2 and H 2 O as the final products. Radicals are stabilized by the presence of multiple carbon substituents that can donate electron density to the electron-deficient carbon.

The chemical explanation of octane ratings rests partly on the stability of radicals produced from the different hydrocarbon fuels. Isooctane has a branched structure and is capable of forming tertiary radicals that are comparatively stable. In contrast, the radicals formed during the combustion of n-heptane, whether primary or secondary, are less stable and hence more reactive, which partly explains why burning n-heptane causes premature ignition and engine knocking.

In Section Consequently, the cis and trans isomers of alkenes generally behave as distinct compounds with different chemical and physical properties. A four-carbon alkene has four possible isomeric forms: three structural isomers, which differ in their connectivity, plus a pair of geometric isomers from one structural isomer 2-butene.

These two geometric isomers are cisbutene and transbutene. The four isomers have significantly different physical properties.

Because this interconversion is energetically unfavorable, cis and trans isomers are distinct compounds that generally have different physical and chemical properties. Acetylide ions are potent nucleophiles that are especially useful reactants for making longer carbon chains by a nucleophilic substitution reaction.

As in earlier examples of such reactions, the nucleophile attacks the partially positively charged atom in a polar bond, which in the following reaction is the carbon of the Br—C bond:.
