The reaction of aldehydes and ketones with ammonia derivative G-NH2 to form compounds containing the group \c=N-G and water is known as_.

Explanation

Option D is correct.Yes, the reaction of aldehydes and ketones with ammonia derivatives is known as addition-elimination. This reaction is a two-step process. Step 1 The ammonia derivative (G-NH2) adds to the carbonyl group of the aldehyde or ketone to form an imine. The imine is a compound that contains a carbon-nitrogen double bond and a hydrogen atom on the nitrogen atom. The following reaction takes place in the first step: RCHO + G-NH2 → RC=N-G + H2O Here, RCHO represents the aldehyde or ketone, and G represents the group attached to the nitrogen atom of the ammonia derivative. Step 2 The imine is then hydrolyzed to form a new compound containing the group \c=N-G and water. The hydrolysis reaction is catalyzed by a base, such as sodium hydroxide (NaOH). The following reaction takes place in the second step: RC=N-G + H2O → RC=N-G + H2O The addition-elimination reaction is a versatile reaction that can be used to synthesize a variety of compounds. For example, it can be used to synthesize Schiff bases, which are important in organic chemistry and biochemistry.
