2) Assign the splitting pattern to each type of protons in these structures. Use the following abbreviations: s= singlet; d=doublet; t=triplet; q=quartet; 5 or more peaks: multiplet. If there is coupling from different sets of protons, then both couplings must be identified. E.G. doublet of triplets: d of t or t of d.
