Cinnamci acid is fomed when `C_(6)H_(5)-CHO` condenses with `(CH_(3)CO_(2))O` in the presence of

A

concentreated `H_(2)SO_(4)`

B

sodium acetate

C

sodium metal

D

anhydrous `ZnCl_(2)`

Text Solution

Verified by Experts

The correct Answer is:
B
When `C_(6)CHO` condneses with `(CH_(3)CO_(2))` O in the presence of sodium acetate then cinnamci aciod is formed. This reaction is called Perkin reaction
`underset("Benzaldehyde")(C_(6)H_(5)-CHO)+ underset("Acetic anhydride")((CH_(3)CHO)_(2)O)overset(CH_(3)CO overset(-)O overset(+)Na) underset(100^(@)C)to underset("Cinnamic acid")(C_(6)H_(5)CH=CHCOOH)+CH_(3)COOH`
