Statement I: In Sandmeyer reaction nucleophiles like

{Cl}^{-}, {Br}^{-}

and

{CN}^{-}

are introduced in benzene ring in the presence of

{Cu}^{+}

ion.

Statement-II : In Gattermann rection nucleophiles are introduced in benzene ring in the presence of copper powder and

HCl.

View answer and explanation

Correct option: A

Both statement I and II are correct

Both statement I and II are correct. Sandmeyer reaction uses Cu+ ions to introduce nucleophiles, and Gattermann reaction uses copper powder and HCl to introduce nucleophiles into the benzene ring.
