Identify product A and B in following reaction R-COOR' [ dry ether ] LiAlH_4 A + B

MHT CET 2022 Chemistry question

Identify product A and B in following reaction

R-COOR'\ \ A + B

(A)A = R – CHOH, B = R' - OHCorrect
(B)A = R – OH, B = R' – H
(C)A = R –COOH, B = R' OH
(D)A = R – CH, B = R' – COOH

Answer: (A)

Solution

Lithium aluminium hydride is a strong reducing agent that reduces the ester group. The acyl part is reduced to a primary alcohol and the alkoxy part leaves as the alcohol : \xrightarrow{LiAlH_4}RCH_2OH$ +
