Question

Semicarbazones undergo acidic nucleophilic addition followed by dehydration to give N-substituted carbonyl derivatives.

(a) True

(b) False

I had been asked this question during an interview for a job.

My question comes from Aldehydes and Ketones Chemical Reactions in division Aldehydes, Ketones and Carboxylic Acids of Chemistry – Class 12

Answer 1

The correct choice is (b) False

For explanation: Semicarbazone is the name of the product formed from the rapid dehydration of the product of the reaction between semicarbazide and aldehyde or ketone in acidic medium. Semicarbazide is the reagent and Semicarbazone is the N-substituted carbonyl derivative.
