The reason should be determined for not forming an amide during the condensation of tertiary amine and carboxylic acid . Concept Introduction: Compounds consist of carbon and hydrogen is known as hydrocarbons. Hydrocarbons are classified as saturated hydrocarbon and unsaturated hydrocarbon . The compound containsat least one nitrogen atom (with one lone pair of electrons) which is linked with hydrogen atoms or alkyl or aryl groups are known as amine.It is a derivative of ammonia. Amides: These are the derivatives of carboxylic acids in which the hydroxyl group is replaced by an ammonia or amine. In carboxylic acid, carbonyl carbon is linked to carbon or hydrogen on one side and on other side linked to a heteroatom such as O, N, S. The general formula is RCOOH, where R is an alkyl group.

Question

Q4: Comparing (3S,4S)-3,4-dimethylhexane and (3R,4S)-3,4-dimethylhexane, which one is optically active? Briefly explain.

Answer 1

Question

Definition Definition Molecules that have multiple bonds between their carbon atoms. Alkenes are hydrocarbons with a double bond between two adjacent carbon atoms (R 2 C=CR 2 ), whereas alkynes are hydrocarbons with a triple bond between two adjacent carbon atoms R-C=C-R . These two groups are known as unsaturated hydrocarbons. They have fewer hydrogen atoms when compared with alkanes with same number of carbon atoms. The general molecular formula for an unsaturated hydrocarbon can be represented as C n H 2n +2 .
