Question

Diisobutylaluminum hydride (DIBALH) can be used to carry out which of the following conversions?

(A)ester to aldehyde
(B)carboxylic acid to ester (C) 2' alcohol to Ketone
(D)aldehyde to carboxylic acid
(E) ester to a Ketone

Answer 1

Answer: Diisobutylaluminum hydride (DIBALH) is a reducing agent that can reduce esters to aldehydes or 2' alcohols to ketones. Therefore, the correct answer is (A) ester to aldehyde and (C) 2' alcohol to ketone.

DIBALH is not capable of converting carboxylic acid to ester or ester to a carboxylic acid, nor can it oxidize an aldehyde to a carboxylic acid.

Explanation: Diisobutylaluminum hydride (DIBALH) is a reducing agent that can reduce esters to aldehydes or 2' alcohols to ketones. Therefore, the correct answer is (A) ester to aldehyde and (C) 2' alcohol to ketone.

DIBALH is not capable of converting carboxylic acid to ester or ester to a carboxylic acid, nor can it oxidize an aldehyde to a carboxylic acid.
