How will you remove traces of aniline present in benzene ?

Text Solution

Verified by Experts

If benzene containing traces of aniline (basic in nature ) is shaken with conc. `H_2SO_4` then aniline dissolves in the acid forming a salt. The acid layer is thus removed. In this way traces of aniline present in benzene can be removed.
`2C_6H_5NH_2+H_2SO_4to(C_6H_5overset(oplus)NH_3)_2SO_4^(2-)`
