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

  1. Both compound 'A' and compound 'B' are dicarboxylic acids
  2. Both compound 'A' and compound 'B' are diols
  3. Compound 'A' is diol and compound 'B' is dicarboxylic acid
  4. Compound 'A' is dicarboxylic acid and compound 'B' is diol

Solution

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