The example of Friedel-Craft's reaction is

A) \[{{x}^{2}}+{{y}^{2}}={{a}^{2}}\]

B) \[{{x}^{2}}+{{y}^{2}}={{a}^{-1}}\]

C) \[f:R\to A\]

D) \[f(x)=\frac{{{x}^{2}}}{{{x}^{2}}+1}\]    

Correct Answer: A

Solution :

In Friedel-Craft's reaction, alkyl substituted benzenes are prepared by the reaction between benzene and alkyl halide in the presence of a Lewis acid\[4.0\times {{10}^{-5}}{{/}^{o}}C\].
