For above chemical reactions, identify the correct statement from the following:

For above chemical reactions, identify the correct statement from the following:

Options

  1. ABoth compound ′A′' A ' and compound ′B′' B ' are dicarboxylic acids
  2. BBoth compound ′A′' A ' and compound ′B′' B ' are diols
  3. CCompound ′A′' A ' is diol and compound ′B′' B ' is dicarboxylic acid
  4. DCompound ′A′' A ' is dicarboxylic acid and compound ′B′' B ' is diol

Correct answer

D. Compound ′A′' A ' is dicarboxylic acid and compound ′B′' B ' is diol

Step-by-step solution

For above chemical reactions, identify the correct statement from the following:

KMnO4{KMnO}_{4} in acidic medium is very strong oxidising agent due to which carboxylic acid is produced from alkene. KMnO4{KMnO}_{4} in neutral medium is not very strong oxidising agent therefore, syn hydroxylation occurs and diol is produced from alkene.
