For a compound to be aromatic, the value of n must be an integer (n = 0, 1, 2…). Since the value of n is not an integer, the given compound is not aromatic in nature. Question 13.13: How will you convert benzene into (i) p-nitrobromobenzene (ii) m-nitrochlorobenzene (iii) p -nitrotoluene (iv) acetophenone (i) Benzene can be converted into p-nitrobromobenzene as: (ii) Benzene can be converted into m-nitrochlorobenzene as: (iii) Benzene can be converted into p-nitrotoulene as: (iv) Benzene can be converted into acetophenone as: Question 13.14: In the alkane H3C–CH2–C(CH3)2–CH2–CH(CH3)2, identify 1°,2°,3° carbon atoms and give the number of H atoms bonded to each one of these. 1° carbon atoms are those which are bonded to only one carbon atom i.e., they have only one carbon atom as their neighbour. The given structure has five 1° carbon atoms and fifteen hydrogen atoms attached to it. 2° carbon atoms are those which are bonded to two carbon atoms i.e., they have two carbon atoms as their neighbours. The given structure has two 2° carbon atoms and four hydrogen atoms attached to it.
