Question : Adding Cl2 to benzene in the presence of AlCl3 is an example of:
Option 1: Elimination reaction
Option 2: Substitution reaction
Option 3: Addition reaction
Option 4: None of the options
Correct Answer: Substitution reaction
Solution : The correct option is Substitution reaction.
A substitution reaction is the addition of chlorine (Cl2) to benzene (C6H6) in the presence of aluminium chloride (AlCl3). This is referred to as electrophilic substitution. One or more hydrogen atoms in the benzene ring are replaced by chlorine atoms during this process. The aluminium chloride functions as a catalyst, creating electrophilic species capable of attacking the benzene ring.
