Answer 1

condensation reaction

here the benzaldehyde and KCN undergoes self condensation to form alpha hydroxy ketone

Answer 2

ALDOL CONDENSATION

Aromatic aldehyde when reflux with alcoholic KCN solution undergoes self condensation to form alpha-hydroxy ketone, the name reaction is​ ALDOL CONDENSATION

DESCRIBING ALDOL CONDENSATION:

* Aldehydes and ketones undergo the aldol reaction if they contain at least one -hydrogen. As a result, the reaction takes place in the presence of alkali (dilute).

* The dilute alkali aids in the synthesis of -hydroxy aldehydes or aldol and -hydroxy ketones or ketol by acting as a catalyst in the reaction.

* Aldol condensation is the name for this reaction. Because two separate functional groups, aldehyde and alcohol, are present in the reaction, the reaction is named after these two products.

* Water molecules are rapidly lost by -hydroxy aldehydes or aldol and -hydroxy ketones or ketol to create, -unsaturated carbonyl compounds.
