PROPYL BENZENE



The 1H spectrum shows three peaks in the range d0-3 which are due to the alkane side-chain. These peaks have an intensity ratio of 2:2:3 which is only consistent with a straight alkyl side-chain.
The 13C spectrum shows three peaks in the range d10-40 due to the alkyl side-chain. This is consistent with the straight chain isomer as there are three chemically different carbon atoms, giving three different peaks. However, this is not consistent with the branched isomer as the two terminal methyl groups would be chemically equivalent, giving only two peaks.
