Q)

# A complex compound which is formed by ligands nitrate and chloride. It gives two moles of AgCl precipitate with $AgNO_{3}$ . What will be its formulae :

( A ) $[Co(NH_{3})_{5}Cl]NO_{3}Cl$
( B ) $[Co(NH_{3})_{4}Cl_{2}]NO_{3}$
( C ) $[Co(NH_{3})_{5}NO_{3}] Cl_{2}$
( D ) $[Co(NH_{3})_{4}Cl NO_{3}]Cl$

From the given option the complex compound which is formed by ligands nitrate and chloride is $[Co(NH_3)_5NO_2]Cl_2$
$[Co(NH_3)_5NO_2]Cl_2\Rightarrow [Co(NH_3)5NO_2]^{2+}+2Cl^−$
$2AgNO_3+ 2Cl^− \Rightarrow 2AgCl+2NO^{−3}$
