Question

Identify B in the given reaction sequence:

• A.

  

• B.

  

• C.

  

• D.

  

Hint:

- The reaction between a nitrile and a Grignard reagent results in the formation of a magnesium complex. - After hydrolysis, the product is an alcohol.

Answer 1

The Correct Option is C

Step 1: In the first step, phenylacetonitrile (C\(_6\)H\(_5\)CN) reacts with magnesium bromide (MgBr) in ether, which forms a Grignard reagent (C\(_6\)H\(_5\)MgBr).
Step 2: The Grignard reagent then reacts with water, which results in the formation of a benzyl alcohol (C\(_6\)H\(_5\)CH\(_2\)OH). Thus, product \( B \) is a benzyl alcohol, which is represented by option (3).
