Great! Your answer is right.

The signal of the proton H^A in

ClCH	=	CH	-	CH₂Cl
M		A		X

is split into

six individual lines, since H^M and H^X are not equivalent. Therefore their spin-spin couplings to H^A are independent from each other. H^A gives rise to a multiplet with

M_A = (n_M + 1) · (n_X + 1).

Did you arrive at a different answer? Check on page 91 for additional explanations.

Continuing from here, what would be the ratio of the intensities of the individual lines in the H^A signal be?
