Identify the product obtained when Grignard reagent reacts with alkyl cyanide followed by acid hydrolysis.

Options

  1. Aan aldehyde
  2. Ba ketone
  3. Ca primary alcohol
  4. Da secondary alcohol

Correct answer

B. a ketone

Step-by-step solution

Grignard reagents ( R'MgX ) react with alkyl cyanides ( R-C N ) to form an imine salt intermediate. R-C N + R'MgX R-C(R')=NMgX Upon acid hydrolysis, the imine salt is converted into a ketone. R-C(R')=NMgX + H₃O^+ R-C(=O)-R' + NH₃ + Mg(OH)X Thus, the final product obtained is a ketone. Answer: a ketone
