Vedclass · Answer

(B) The reaction between a ketone (cyclobutanone) and semicarbazide $(H_2N-NH-CO-NH_2)$ is a nucleophilic addition-elimination reaction. In this reaction,the carbonyl oxygen of the ketone is replaced by the nitrogen atom of the semicarbazide,resulting in the formation of a semicarbazone. The general structure of a semicarbazone is $R_2C=N-NH-CO-NH_2$. For cyclobutanone,the structure is a cyclobutane ring double-bonded to a nitrogen atom,which is attached to an $NH$ group,which is attached to a carbonyl group,which is attached to an $NH_2$ group. This matches the structure shown in option $B$.

The semicarbazone of cyclobutanone is represented as:
