Vedclass · Answer

(A) When glycerol is heated with potassium bisulphate $(KHSO_4)$,it undergoes dehydration to form acrolein $(CH_2=CH-CHO)$,which is compound $(A)$.When acrolein $(CH_2=CH-CHO)$ is reduced using lithium aluminium hydride $(LiAlH_4)$,the aldehyde group is reduced to a primary alcohol group,resulting in the formation of allyl alcohol $(CH_2=CH-CH_2OH)$,which is compound $(B)$.

${\text{Glycerol}}$ $\xrightarrow{KHSO_4} (A)$ $\xrightarrow{LiAlH_4} (B)$; $(A)$ and $(B)$ are respectively:
