13C NMR is a technique in which the total number of signals represents the number of unique carbon atoms in a molecule. Propose a structure that is consistent with the following data. a. The IR includes peaks at 1603 and 1495 cm^-1
b. The 13c NMR has a total of 7 signals
c. The compound has one acidic proton.

The balanced equation is expressed:

H2S + 3/2O2 --> SO2 + H2O 

We are given the amount of O2 to be used in the reaction. This will be the starting point for our calculations. We do as follows:

6 mol O2 ( 1 mol SO2 / 3/2 mol O2 ) = 4 moles SO2 produced

Hope this answers the question. Have a nice day.
