Consider the following set of reactions.
What are A and B respectively?
- A \(\mathrm{LiAlH}_4, \mathrm{H}_2 \mathrm{O} \quad ; \mathrm{H}_2 / \mathrm{Ni}\)
- B \(\mathrm{Na} / \mathrm{Hg}, \mathrm{C}_2 \mathrm{H}_5 \mathrm{OH}\); DIBAL-H, \(\mathrm{H}_2 \mathrm{O}\)
- C DIBAL-H, \(\mathrm{H}_2 \mathrm{O} \quad ; \mathrm{LiAlH}_4, \mathrm{H}_2 \mathrm{O}\)
- D \(\mathrm{Na} / \mathrm{Hg}, \mathrm{C}_2 \mathrm{H}_5 \mathrm{OH} ; \mathrm{H}_2 / \mathrm{Ni}\)
Answer & Solution
Correct Answer
(B) \(\mathrm{Na} / \mathrm{Hg}, \mathrm{C}_2 \mathrm{H}_5 \mathrm{OH}\); DIBAL-H, \(\mathrm{H}_2 \mathrm{O}\)
Step-by-step Solution
Detailed explanation
A is DIBAL-H, \(\mathrm{H}_2 \mathrm{O}\) for partial reduction of nitrile to aldehyde. B is \(\mathrm{LiAlH}_4, \mathrm{H}_2 \mathrm{O}\) for full reduction of ester to primary alcohol. Thus, A and B are DIBAL-H, \(\mathrm{H}_2 \mathrm{O}\) and…
