Vedclass · Answer

(D) The reaction of glycerol with acetic anhydride $(Ac_2O)$ is an acetylation reaction where each hydroxyl $(-OH)$ group is replaced by an acetyl group $(-COCH_3)$.In this process,an $H$ atom is replaced by a $COCH_3$ group.The net change for each $-OH$ group is the addition of $C_2H_2O$ (since $COCH_3 - H = C_2H_2O$).Glycerol has three $-OH$ groups,so for three groups,the total increase in the molecular formula is $3 	imes (C_2H_2O) = C_6H_6O_3$.

In the above reaction,the molecular formula of glycerol increases by:
