Give reasons to support the answer: 

(A) Presence of Alpha hydrogen in aldehydes and ketones is essential for aldol condensation. 

Answer

  • The alpha hydrogen atoms are acidic in nature due to the presence of electron withdrawing carbonyl group. 
  • These can be easily removed by a base and the carbanion formed is resonance stabilised. 
  • The more stable a product is, the higher the spontaneity of the reaction is- meaning, the reaction is more likely to occur .

Therefore, the presence of Alpha hydrogen in aldehydes and ketones is essential for aldol condensation.
