Question

Describe the synthesis preparation of Aldol condensation products

Answer 1

Carbonyl compounds in which – H atoms are present, undergoes to self condensation in presence of dilute alkali or dilute base. The product formed contains both –OH and >C = O group. So, the compound is called Aldol or Ketol which on –elimination gives unsaturated carbonyl compound. The complete reaction is called ‘Aldol – Condensation’. Formaldehyde cannot show aldol condensation due to absence of –Hydrogen atoms.

  

In aldol condensation, if we take two different type of aldehyde or ketone then it is called mixed aldol condensation.

If you have any doubt please comment in comment box. Thanks in advance.
