Vedclass · Answer

(C) The reaction of acetone with semicarbazide produces acetone semicarbazone and water.The chemical reaction is: $(CH_3)_2C=O + H_2N-NH-CONH_2 \rightarrow (CH_3)_2C=N-NH-CONH_2 + H_2O$.In the structure of acetone semicarbazone,$(CH_3)_2C=N-NH-CONH_2$,we can count the nitrogen atoms:$1$. One nitrogen atom is in the $C=N$ group.$2$. One nitrogen atom is in the $-NH-$ group.$3$. One nitrogen atom is in the $-NH_2$ group.Therefore,the total number of nitrogen atoms in a molecule of acetone semicarbazone is $3$.

The number of nitrogen atoms in a semicarbazone molecule of acetone is $.....$
