Chemistry - Aromatic Hydrocarbon Question with Solution | TestHub
The major product of the following reaction is:
Options:
Answer:
Solution:
Question Explanation: The question asks for the major product obtained from an electrophilic aromatic substitution reaction.
Concept: This question is based on Electrophilic Aromatic Substitution (Friedel-Crafts reaction).
Solution:
Step 1: A carbocation intermediate forms, simultaneously with the phenolic OH group complexing with AlCl₃ and becoming deactivated.
Step 2: The electrophile attacks the para-position relative to the methyl group and deprotonates.
Step 3: The carbon with the alcoholic OH group develops carbocationic character due to complexation with AlCl₃.
Step 4: An intramolecular Friedel-Crafts reaction occurs at the para-position to the phenolic OH group, and then deprotonation yields the final product.
