Current Question (ID: 21317)

Question:

$\text{The reaction of toluene with Cl}_2 \text{ in the presence of FeCl}_3 \text{ gives predominantly:}$

Options:

1. $\text{Benzoyl chloride}$
2. $\text{Benzyl chloride}$
3. $\text{o-and p-Chlorotoluene}$
4. $\text{m-Chlorotoluene}$

Solution:

$\text{Hint: Electrophilic aromatic substitution reaction and the function of FeCl}_3 \text{ is to generate Cl}^+. $ $\text{When toluene reacts with chlorine (Cl}_2\text{) in the presence of ferric chloride (FeCl}_3\text{), the major products are o-chlorotoluene and p-chlorotoluene. This reaction is an example of an electrophilic aromatic substitution reaction.}$ $\text{The methyl group in the benzene ring activates the ring at the ortho and para positions more than the meta position, which is why the reaction occurs at these positions.}$
