  2. Bm -cresol only
  3. Cmixture of o -and p -cresol
  4. Dp -cresol only

Correct answer

C. mixture of o -and p -cresol

Step-by-step solution

Phenol is an electron-rich aromatic compound due to the presence of the hydroxyl group, which is strongly activating and ortho/para-directing. Friedel-Crafts alkylation involves the reaction of an aromatic ring with an alkyl halide in the presence of a Lewis acid catalyst like AlCl₃ . However, phenol reacts with the Lewis acid catalyst to form a phenoxide-aluminum complex. This complex deactivates the ring towards electrophilic substitution and makes the reaction difficult. Despite this, under specific conditions,
