IIT JEEIIT JEE 1979The p-Block Elements - Part2

Solution:

(i) $Ca(OH)_2 + Cl_2 \xrightarrow{40^\circ\, C} CaOCl_2 + H_2O$
(ii) $3Cu + 8HNO_3 (dil) \longrightarrow 3Cu(NO_3 )_2+ 4H_2O + 2NO$
(iii) $2NaCl + 2H_2SO_4 + MnO_2 \longrightarrow Na_2SO_4 + MnSO_4 + 2H_2O + Cl_2$
(iv) $Al_2O_3 + 3C + 3Cl_2 \xrightarrow{\, \, \Delta\, \, } 2AlCl_3 + 3CO$
