For each of the above compounds, do the following: 1. List the wave numbers of all the IR bands in the 1350-4000 cm-1 region. For each one, state what bond or group it represents. 2. Label equivalent sets of protons with lower-case letters. Then, for each 1H NMR signal, give the ô value, the,type of splitting (singlet, doublet etc.), and the number of protons it represents. letter õ value splitting # of protons
