Vedclass · Answer

(C) When ethanal $(CH_3CHO)$ reacts with semicarbazide $(NH_2NHCONH_2)$,a condensation reaction occurs where a molecule of water is eliminated to form a semicarbazone. The terminal $-NH_2$ group of semicarbazide is involved in the reaction with the carbonyl group of the aldehyde.The reaction is as follows:$CH_3CHO + NH_2NHCONH_2 \rightarrow CH_3CH=NNHCONH_2 + H_2O$The correct structure of the product,acetaldehyde semicarbazone,is $H_3C-CH=N-NH-C(=O)-NH_2$.

Which among the following is the correct structure of the semicarbazone formed when ethanal reacts with semicarbazide?
