Summary: In the first example, hydrogen indicated with arrow gives dd (doublet of doublet). In the second example, hydrogen indicated with arrow gives t (triplet). In the third example, hydrogen indicated with arrow gives s (singlet). In the forth example, hydrogen indicated with arrow gives dd (doublet of doublet).

Indicate the splitting pattern for each hydrogen type in the
following compounds by entering the appropriate letter(s) into each
box. (singlet = s; doublet = d; doublet of doublets = dd; triplet =
t; quartet = q; for signal splitting caused by more than three
adjacent hydrogens, enter m = multiplet.)
