Given that reduction of 2-butanone with NaBH 4 yields 2-butanol. Whether the product is chiral and optically active or not is to be stated and explained. Concept introduction: Aldehydes and ketones can be reduced to alcohols using NaBH 4 . It reduces the esters very slowly and does not reduce carboxylic acids. The reduction can be carried out in either water or alcohol solution. Ketones are reduced to 2 0 alcohols. To state and explain: Whether 2-butanol obtained by the reduction of 2-butanone with NaBH 4 is chiral and optically active or not.

Question

(a) Why does p-dichlorobenzene have a higher m.p. than its o- and m-isomers?(b) Why is (±)-Butan-2-ol optically inactive?

Answer 1

Question

Definition Definition Class of organic compounds that contain a carboxyl group ( - COOH ) and has a general formula R - COOH or R - CO 2 H , where R refers to the alkyl, alkenyl, aryl, or other groups. They can undergo different chemical reactions, such as acid-base reactions, esterification, and oxidation. These are essential components of living organisms, playing important roles in metabolic processes, signaling, and as pharmaceuticals.
