Question

Write electronic configuration of element 2=25 write a note on aldol condensation​

Answer 1

Answer:

(a) It is a characteristic reaction of aldehydes and ketones containing active α – H atoms. The carbon atom adjacent to carbonyl carbon is called α –C and the H-atom attached to α –C is known as α – H atoms.

(b) When two molecules of Aldehyde or Ketones containing active α – H atom are warmed in presence of dilute base or dilute acid, they undergo self-condensation to given β Hydroxy aldehyde (aldol) or β Hydroxy ketone (ketol) respectively. This reaction is known as aldol condensation. The Aldol or Ketol undergoes dehydration on heating to form unsaturated aldehyde or ketone.

Eg. Aldol condensation of Acetaldehyde
