Question

I already have the degrees of unsaturation (question 1) and just need 2 and 3

PROBLEMS
1. For each spectral data set, determine the general type (C, CH, CH₂, or CH3) of each carbon signal.
Are there any signals representing more than one carbon? How many degrees of unsaturation are
there in each formula?
a. CsH16O2
14.0, q
14.3, q
17.1, q
20.4, t
36.0, t
39.4, d
60.0, t
176.6, s
b. C6H1003
54.1, q
107.1, d
131.2, d
c. C7H16O
14.4, q
16.6, q
20.1, t
35.5, t
35.6, d
68.3, t
d. C7H8
50.2, d
75.3, t
143.3, d
2. For each spectral data set in (1.) above, determine the general types of carbons (carbonyl, C=C, or
13,
alkyl) for each ¹3C NMR signal.
3. For each spectral data set in (1.), determine the number of identical carbons generating each signal.
