Identify ' A ' in the following reaction. A + Acetyl chloride [ AlCl ₃] anhydrous 1 - chloroacetophenone +4 -chloroacetophenone

Step-by-step solution

The given Friedel-Crafts acylation reaction produces both 1-chloroacetophenone (ortho-substituted isomer) and 4-chloroacetophenone, indicating chlorobenzene as the aromatic substrate, with chlorine directing electrophilic substitution to ortho and para positions. From acetyl chloride CH ₃ COCl and anhydrous AlCl ₃ , the acyl group attaches to positions activated by chlorine. Benzene yields only acetophenone, toluene gives methylacetophenones, and phenol produces hydroxyacetophenones, all inconsistent with the chlor
