Reaction of ester with Grignard reagent give rise to

• A

  Primary alcohol
• B

  Secondary alcohol
• Correct answer
  C

  Tertiary alcohol
• D

  Ketone

Solution

All esters (except $\mathrm{H}\mathrm{C}\mathrm{O}\mathrm{O}{\mathrm{C}}_2{\mathrm{H}}_5)$ on reaction with Grignard's reagent give rise to tertiary alcohol.

Hence, the correct answer is option: 'C'.
