Vedclass · Answer

(B) Step $1$: The Hofmann bromamide degradation reaction involves the conversion of an amide $(RCONH_2)$ to a primary amine $(RNH_2)$ using $Br_2$ and $KOH$ (or $NaOH$).Step $2$: In this reaction, the carbonyl group $(-CO-)$ is removed as a carbonate $(K_2CO_3)$, not reduced to a $-CH_2-$ group.Step $3$: Since one carbon atom is lost during the reaction, the resulting amine has one carbon atom less than the parent amide, making its molar mass lower.Step $4$: Therefore, the statement that the $-CO-$ group is reduced to a $-CH_2-$ group is false.
