"WebPick a hydrogen on the ethane. It will seem strange, but that hydrogen ignores the other two hydrogen on the same carbon but concentrates on the other three neighboring hydrogens as it sends a signal to the NMR (pardon the anthropomorphism). The signal the NMR recieves is based on the n+1 rule. " - Ethane h nmr
