Which of the following is the maximum multiplicity observed for H_b protons in the following compound? Assume that J_ab and J_bc values are different.

Question

Quizplus · Accepted Answer

The maximum multiplicity for H_b protons in the given compound can be achieved by considering the neighboring protons. Assuming J_ab and J_bc values are different, the H_b proton can show a maximum of 9 peaks in its multiplet if it has 4 neighboring protons (2 on each side) with different coupling constants. This would result in a pattern of dddd (doublet of doublets of doublets of doublets). Hence, the correct answer is option A).
