![Answer the following:
(i) If nitration of pyridine is carried out using 'mixed acid (HNO3/H2SO4) i.e. electrophilic substitution,
which position would be substituted? (Give a reason);
(ii) For nucleophilic substitution, we usually need a leaving group (other than H) on the pyridine ..
give two examples of suitable substituents;
(iii) Now give two examples of nucleophiles that might typically be involved;
