Interpretation:
The expected product has to be drawn for the given reaction with the information provided.
Concept Introduction:
Addition reactions are the one in which the groups are added to an unsaturated double bond. The double bond is destroyed because the groups are added across the double bond. If the considered
When two similar groups are added across a double bond, regiochemistry is irrelevant. When adding two different groups across the double bond of an unsymmetrical alkene, the regiochemistry becomes relevant. In simple words, it can be said that, when two different groups are added across a double bond, then regiochemistry becomes relevant.
Markovnikov Addition
In the vinylic bond, if the bulky group gets substituted in the carbon atom that is more substituted means, it is known as Markovnikov’s addition.
anti-Markovnikov Addition
In the vinylic bond, if the bulky group gets substituted in the carbon atom that is less substituted means, it is known as anti-Markovnikov’s addition.
Stereochemistry can also be determined for the product obtained by the way of addition of groups that adds across the double bond. If the two groups add in the same side of the plane means it is known as syn addition and if the two groups add in the opposite side of the plane means it is known as anti addition. This can be done by considering the given alkene in a planar form by using wedge and dash bonds.

- Consider the data below to answer the following questions. Cyanohydrins are important intermediates in the synthesis of a-hydroxycarboxylic acids from ketones and aldehydes. The nitrile functional group can be hydrolyzed by aqueous acid to yield a carboxylic acid. Nitriles can also be hydrolyzed to carboxylic acids using aqueous base. Unfortunately, when a cyanohydrin is treated with aqueous base the original carbonyl compound is isolated.
