Question

Identify the main product of following reaction

• A. \(\text{R}-\text{COOH}\)
• B. \(\text{RCOR}^'\)
• C. \(\text{RCHO}\)
• D. \(\text{R CH}_2\text{ OH}\)

Hint:

DIBAL-H partially reduces esters to aldehydes at low temperature.

Answer 1

The Correct Option is C

Step 1: Reagent:
DIBAL-H stops the reduction at the aldehyde stage because the intermediate is stable until water is added.

Step 2: Outcome:
The acyl part becomes $\text{-CHO}$ and the alkoxy part leaves as alcohol. So the product is RCHO (C).

Final Answer:
RCHO. \[ \boxed{\text{(C)}} \]
