    A)Explain why the 3-pentanol 13C-NMR spectrum contains three peaks while the trans and cis-2-pentene spectra contain five peaks (note that 13C-NMR gives a peak for each unique carbon, i.e. identical carbons show up as the same peak).

    Well, this is not that difficult to understand.

    There are only three kinds of carbon atoms in 3-pentanol. Draw it out. You'll see this is so. It's a symmetrical molecule where C1 is identical to C5, C2 is ...
