Transcription of this question: Xylene is a derivative of benzene. One isomer is 1 ,4-dimethylbenzene.H3CCH3(a) State the number of iH NMR signals for this isomer of xylene and the ratio in whichthey appear.Number of signals:Ratio:(b)Draw the structure of one other isomer of xylene which retains the benzene ring.(c)Bromine reacts with alkanes.0)(ii)Identify the initiation step of the reaction and its conditions.1 ,4-dimethylbenzene reacts as a substituted alkane. Draw the structures of thetwo products of the overall reaction when one molecule of bromine reacts withone molecule of 1 ,4-dimethylbenzene.
