Question

$C_6{H}_6+C_6{H}_{5}Cl\stackrel{anhyd.AlC{l}_3}{\to }P.$
In the above reaction, product $P$ is:

• A.
• B.
• C.
• D. No reaction

Answer 1

The correct option is D No reaction

This is an example of Friedel-Crafts alkylation reaction. In this reaction, attacking electrophile is an alkyl carbocation $\left(R^{+}\right)$ made available by the reaction of alkyl halide and an anhydrous lewis acid.
When the phenyl chloride reacts with $AlC{l}_3$, it gives phenyl cation which is unstable because formed cation is not stabilised by resonance, so it will not be formed. Hence, there will be no reaction.
