A

conc. `H_3PO_4`

B

conc. HCl/`ZnCl_2`

C

D

conc. HBr

Text Solution

Verified by Experts

The correct Answer is:
A
The acid used must have a non-nucleophilic anion. Since `Cl^-` and `Br^-`ions are good nucleophiles, therefore, HCl and HBr will give their corresponding halides , therefore, `H_3PO_4` is the correct option.
