The reaction sequence(s) that would lead to

o

-xylene as the major product is (are)

(A)(see structure)
✓ Correct
(B)(see structure)
✓ Correct
(C)(see structure)
(D)(see structure)

Answer: (A), (B)

Solution

Options (A) and (B) both lead to *o*-xylene as the major product through the given reaction sequences. In (A), the reaction proceeds via a specific pathway that directs the substituents to ortho positions. Similarly, (B) follows a mechanism that results in ortho-substitution. Options (C) and (D) do not yield *o*-xylene as the major product due to different directing effects and reaction pathways.
