Identify 'A' in the following reaction. gathered A + Acetyl chloride Anhydrous AlCl ₃ 1-Chloroacetophenone + 4-Chloroacetophenone gathered

Step-by-step solution

The Friedel–Crafts acylation of an aromatic compound A with acetyl chloride ( CH₃COCl ) and anhydrous AlCl₃ yields 1-chloroacetophenone and 4-chloroacetophenone, indicating the substrate is a chlorobenzene derivative. Benzene would yield acetophenone ( C₆H₅COCH₃ ) without chloro substituents. Chlorobenzene undergoes electrophilic substitution with acetyl chloride, where chlorine is ortho–para directing, giving primarily 2-chloroacetophenone and 4-chloroacetophenone. Note that 1-chloroacetophenone is a common name f
