Write structures of compounds A,B and C ...

Write structures of compounds A,B and C in each of the following reactions:
(i) `C_(6)H_(5) Br overset("Mg/dry ether")rarr A underset((b)H_(3)O^(+))overset((a) CO_(2)(g))rarr B overset(PCl_(5))rarr C`
(ii) `CH_(3)CN underset((b) H_(3)O^(+))overset((a) SnCl_(2)//HCl)rarr A overset("dil."NaOH)rarr B overset(Delta)rarr C`
