In the given reactions sequence, the major product 'C' is:

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

Answer: (B)

Solution

The reaction sequence involves electrophilic aromatic substitution. The molecular formula C₈H₁₀ gives degree of unsaturation DU = 9 - 5 = 4, indicating a benzene ring. The nitration occurs at the para position relative to the vinyl group due to its activating and ortho/para-directing nature. The major product C is para-nitrostyrene (option B).
