Options

  1. ACorrect statements regarding alkyl halides (R - X) among the following are: A. Alcohol being less polar solvent as
  2. BCorrect statements regarding alkyl halides (R - X) among the following are: A. Alcohol being less polar solvent as
  3. CCorrect statements regarding alkyl halides (R - X) among the following are: A. Alcohol being less polar solvent as
  4. DCorrect statements regarding alkyl halides (R - X) among the following are: A. Alcohol being less polar solvent as

Correct answer

C. Correct statements regarding alkyl halides (R - X) among the following are: A. Alcohol being less polar solvent as

Step-by-step solution

In the first step formaldehyde undergoes cross aldol reaction with isobutyraldehyde to form (A)and then the product(A) forms cyanohydrin (B)with KCN, which on hydrolysis forms a compound containing carboxylic acid group and finally this molecule undergoes intramolecular esterification to form (C) a stable compound.
