Question

The product(s) in the following transformation is(are) 

Hint:

Remember that cyanohydrins can be reduced to alcohols using LiAlH\(_4\), and subsequent treatment with NaNO\(_2\) results in the elimination of the diazonium group.

Answer 1

Step 1: Understanding the reaction sequence.
1. Step 1 (NaCN/H\(_3\)O\(^+\)): This step involves a nucleophilic substitution by cyanide on a carbonyl compound, leading to the formation of a cyanohydrin intermediate.
2. Step 2 (LiAlH\(_4\)): LiAlH\(_4\) is a strong reducing agent that reduces the cyanohydrin group to an alcohol group.
3. Step 3 (NaNO\(_2\)/HCl): The nitrous acid treatment will likely lead to the formation of a diazonium salt, followed by elimination to form the desired product.
Step 2: Conclusion.
The major product involves the formation of an alcohol group from the cyanohydrin intermediate.
Final Answer: \[ \boxed{\text{The major product is the alcohol (C).}} \]
