Question

Which of the following statements are correct about the following reactions:
$RCOOH+LiAl{H}_4\to$

• A. First step in the above reaction is
  $RCOOH+LiAl{H}_4\to RCOO{O}^{\ominus }{Li}^{\oplus }+H_2+Al{H}_3$
• B. Second step is the transfer of $H^{\ominus }$ ion from $Al{H}_3$ to $(C=O)$ of $RCOO{O}^{\ominus }$
• C. The intermediate product $(RCH=O)$ is formed
• D. $(RCH=O)$ is further reduced to $R{CH}_2{O}^{\ominus }$ which on acidification gives $R{CH}_{2}OH$

Answer 1

Answer: (A), (B), (C), (D)

The correct options are
A Second step is the transfer of $H^{\ominus }$ ion from $Al{H}_3$ to $(C=O)$ of $RCOO{O}^{\ominus }$
B $(RCH=O)$ is further reduced to $R{CH}_2{O}^{\ominus }$ which on acidification gives $R{CH}_{2}OH$
C First step in the above reaction is
$RCOOH+LiAl{H}_4\to RCOO{O}^{\ominus }{Li}^{\oplus }+H_2+Al{H}_3$
D The intermediate product $(RCH=O)$ is formed

(a), (b), (c), (d) are the steps of mechanism of reduction of $RCOOH$ to $R{CH}_{2}OH$ by $LAH$
