Question

Match the following reactions with their names:

(Reaction)	(Name of the reaction)
(P)	(1) Perkin reaction
(Q)	(2) Cannizzaro reaction
(R)	(3) Aldol Condensation
(S)	(4) Haloform reaction
	(5) Pinacol pinacolone rearrangement

Answer 1

P - (1), Q - (3), R - (5), S - (2)

Answer 2

• Reaction (P): Benzaldehyde + Acetic anhydride + Sodium acetate $\rightarrow$ Cinnamic acid. This is the Perkin reaction.

• Reaction (Q): Two molecules of acetone in the presence of a base $\rightarrow$ $\alpha, \beta$-unsaturated ketone. This is Aldol Condensation.

• Reaction (R): Vicinal diol (2,3-dimethylbutane-2,3-diol) under acidic conditions $\rightarrow$ Ketone (3,3-dimethylbutan-2-one). This is Pinacol pinacolone rearrangement.

• Reaction (S): Formaldehyde + concentrated NaOH $\rightarrow$ Formate + Methanol. This is Cannizzaro reaction.
