1. IR – circle and label each type of bond present directly on
the spectra. Label the type of bond each
peak represents (For example, instead of just saying alkane, you
could say C-H alkane, or Csp3-H).
2. 13C-NMR and 1H-NMR – Draw out the skeletal structure of the
compound, label the H’s a, b, c’s and
the C’s 1, 2, 3’s. Then label all signals on the NMR with those
corresponding letters/numbers.).
3. Please show your calculations for degrees of unsaturation and
integration ratios on one of the
previous handout pages in the margins.
*On each handout page please draw out the skeletal structure of
your unknown.
