Question

2. How many peaks will be observed for ethane in PMR spectroscopy?
(a) Two
(b) One
(c) Three
(d) Zero​

Answer 1

4 peaks

Using the n+1 rule, the hydrogens on one carbon couple to the 3 hydrogens on the adjacent carbon. If n=3 therefore 3+1=4 peaks would be seen. On the NMR spectra of Ethane you would only see a quartet
