Deduce the structures of compounds given from the
spectra provided assigning all 1H and 13C signals (1H on the front
and 13C on the back). All spectra were taken in CDCl3. The peaks
are designated as follows: s=singlet, bs=broad singlet, d=doublet,
t=triplet, q=quartet, pent=pentet(quintet), sext=sextet,
sept=septet, m=multiplet, d of d=double of doublet, etc. Draw the
structure of each compound below the spectra. Label and assign all
signals for both the 1H and 13C spectra.
