The major product of following reaction is: R-C≡N (1) AlH(i-Bu)2 (2) H2O

1. RCHO
2. RCOOH
3. RCONH2
4. RCH2NH2

Correct answer: RCHO

Solution

The reaction involves the reduction of a nitrile (R-C≡N) using a bulky aluminum hydride (AlH(i-Bu)2), which selectively reduces the nitrile to an aldehyde (RCHO) rather than further reducing it to an amine or carboxylic acid.
