हिन्दीIdentify the suitable reagent for the following conversion. \( \begin{array}{c} \text{O} \\ \parallel \\ \text{C-OCH}_3 \end{array} \longrightarrow \text{CHO} \)
Correct answer · Option 2
(i) \( \text{AlH(iBu)}_2 \) (ii) \( \text{H}_2\text{O} \)
Explanation
DIBAL-H (Diisobutylaluminium hydride, \( \text{AlH(iBu)}_2 \)) selectively reduces esters (\( -\text{COOCH}_3 \)) to aldehydes (\( -\text{CHO} \)) at low temperatures followed by hydrolysis.
