(a) $2PCl_5 + H_2SO_4 \longrightarrow 2POCl_3 + 2HCl + SO_2Cl_2$
(b) $2NaOH + H_2SO_4 \longrightarrow Na_2SO_4 + H_2O$
(c) $NaCl + H_2SO_4 \longrightarrow NaHSO_4 + HCl$
(d) $2HI + H_2SO_4 \longrightarrow I_2 + SO_2 + 2H_2O$

Answer 1

d option becaz oxidising nature of h2so4. in last rexn shown hl convert in l2 where l has -1 oxidation state but after rex it is l2 means 0 oxidation sate
