What is the molecular formula of the product formed when benzene is reacted with ethyl chloride in presence of anhydrous aluminium chloride?
- A \(\mathrm{C}_8 \mathrm{H}_{10}\)
- B \(\mathrm{C}_6 \mathrm{H}_6\)
- C \(\mathrm{C}_8 \mathrm{H}_8\)
- D \(\mathrm{C}_6 \mathrm{H}_5 \mathrm{Cl}\)
Answer & Solution
Correct Answer
(A) \(\mathrm{C}_8 \mathrm{H}_{10}\)
Step-by-step Solution
Detailed explanation
In presence of a Lewis acid (like \(\mathrm{AlCl}_3\) ), benzene gives electrophilic substitution reaction with alkyl halide. This is called Friedel-Craft alkylation.
