Question

The function of FeCl3 in chlorination of benzene is produce
(a) Cl (b) Cl-
(c) Cl+
(d) FeCl2

Answer 1

Answer:

Fecl3

Explanation:

Benzene reacts with chlorine or bromine in an electrophilic substitution reaction, but only in the presence of a catalyst. The catalyst is either aluminium chloride (or aluminium bromide if you are reacting benzene with bromine) or iron.

Strictly speaking iron isn't a catalyst, because it gets permanently changed during the reaction. It reacts with some of the chlorine or bromine to form iron(III) chloride, FeCl3, or iron(III) bromide, FeBr3.

These compounds act as the catalyst and behave exactly like aluminium chloride in these reactions.

Answer 2

Answer:

The correct answer of this question is FeCl2.

Explanation:

Given - The function of FeCl3 in chlorination of benzene.

To Find - Write the function of FeCl3 in chlorination of benzene .

FeCl2.

In an electrophilic substitution process, benzene interacts with chlorine or bromine, but only in the presence of a catalyst. Aluminium chloride (or aluminium bromide if you're reacting benzene with bromine) or iron serve as catalysts.

Iron isn't strictly speaking a catalyst because it undergoes permanent alteration during the reaction. It forms iron(III) chloride, FeCl3, or iron(III) bromide, FeBr3, when it interacts with some chlorine or bromine.

In these reactions, these molecules act as catalysts and behave identically like aluminium chloride.
