Does iodine react with benzene?
Does iodine react with benzene?
Iodine forms iodine cation in the presence of acid, which then reacts with benzene to form iodobenzene, water, and nitrogen dioxide.

Is it possible to Iodinate benzene using ICL with AlCl3?
since iodine is less electronegative than chlorine, therefore , AlCl3 reacts with IC l to form iodonium ion (I+) as the electrophile which subsequently reacts with benzene to form iodobenzene.
Why iodine does not react with benzene?
For the halogens, the electronegativity and electrophilicity decrease from F to I in the periodic table. Fluorine is most electrophilic, and Iodine is least. Therefore, Fluorination is highly reactive, and Iodination is highly unreactive for electrophilic aromatic substitution reactions.
What happens when chlorine reacts benzene?
Benzene reacts with chlorine or bromine in the presence of a catalyst, replacing one of the hydrogen atoms on the ring by a chlorine or bromine atom. The reactions happen at room temperature. It reacts with some of the chlorine or bromine to form iron(III) chloride, FeCl3, or iron(III) bromide, FeBr3.

What is iodobenzene used for?
Iodobenzene is used in various C-C coupling reactions. It can be used in the preparation of iodobenzene dichloride, which is employed as an oxidant to oxidize alcohols to carbonyl compounds and as a chlorinating agent.
Why is the reaction of benzene with iodine not possible in presence of AlCl3?
This is because the electronegativity of iodine is less than that of chlorine. The iodonium ion acts as an electrophile. We know that benzene is a planar molecule and has a cloud of delocalised electrons above the plane of the ring.
Why does chlorination of benzene require a catalyst?
In electrophilic aromatic substitutions, a benzene is attacked by an electrophile which results in substition of hydrogens. However, halogens are not electrophillic enough to break the aromaticity of benzenes, which require a catalyst to activate.
