Question

1) Which of the following compounds will undergo Friedel-Crafts alkylation with
(CH3)3CCl, AlCl3 most rapidly?

A) acetophenone

B) iodobenzene

C) anisol

D) Phenol

2) In electrophilic aromatic substitution reactions the -NH2 group is an o,p-director because:

A) it donates electron density to the ring by induction and destabilizes the meta sigma complex.

B) it donates electron density to the ring by resonance and stabilizes the ortho and para sigma
complexes.

C) it donates electron density to the ring by induction and stabilizes the ortho and para sigma
complexes

D) it donates electron density to the ring by resonance and destabilizes the meta sigma complex.

3) The nitration of phenol:

A) proceeds more rapidly than the nitration of benzene and yields predominantly the meta
product.

B) proceeds more rapidly than the nitration of benzene and yields predominantly the ortho, para
products.

C) proceeds more slowly than the nitration of benzene and yields predominantly the meta
product.

D) proceeds more slowly than the nitration of benzene and yields predominantly the ortho, para
products.
