Colouration of `Br_(2)//C Cl_(4)` will be discharged by

A

Cinnamic acid

B

Benzoic acid

C

o-phthalic acid

D

Acetophenone

Text Solution

Verified by Experts

The correct Answer is:
A
Cinnamic acid reacts with bromine in carbon tetrachloride to give dibromocinnamic acid.
`underset("Cinnamic acid")(C_(6)H_(5)CH =CHCOOH+ Br_(2)) overset(CCl_(4))to underset("Dibromocinnamic acid")(C_(6)H_(5)overset(Br)overset(|)CH- overset(Br)overset(|)CHCOOH)`
