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

Options

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

Correct answer

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

Step-by-step solution

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