Question:

A compound A reacts with H2 over Pd/C to give methylcyclohexane. A colleague, A1 Keen, has deduced that the compound must be either 1-methylcyclohexene or 3-methylcyelohexene. You have been called in as a consultant to help Keen decide between these two structures. What evidence would you look for in the proton NMR spectrum to decide between these two possibilities?
