splitting patterns lastly let’s discuss
Splitting Patterns Lastly, let's discuss why some signals are comprised of only a single peak, called a singlet, while other signals exhibit splitting, and may appear as a doublet, triplet, quartet, quintet, sextet, septet, octet, nonet, etc. Splitting is due to neighboring H's. That is, H's that are separated by 3 covalent bonds are called "neighbors". Each neighbor splits a signal, and the pattern observed matches the N+1 rule: the number of peaks observed is...

IMG_AC44821026C2-1.jpegFor each H labeled a-f determine which splitting we are expected to see. Assume octets on all Cs are filled. Options: Singlet, Doublet, Triplet, quartet, Quintet, Sextet, Septet
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.
