Among the following reagents, which one can converts ester into aldehyde?
- A \(\mathrm{AlH}(j-\mathrm{Bu})_2\)
- B \(\mathrm{Sn}+\mathrm{HCl}\)
- C \(\mathrm{H}_2 / \mathrm{Pd}, \mathrm{BaSO}_4\)
- D DIBAL-H
Answer & Solution
Correct Answer
(D) DIBAL-H
Step-by-step Solution
Detailed explanation
DIBAL-H is diisobutyl aluminium hydride. It is a reducing agent with formula \(\left[i-\mathrm{Bu}_2 \mathrm{AlH}\right]_Z\). It is used to convert ester into aldehyde. Hence, (d) is the correct answer.
