A) \[[Co{{(N{{H}_{3}})}_{5}}(N{{O}_{2}})]C{{l}_{2}}\]
B) \[[Co{{(N{{H}_{3}})}_{5}}Cl][Cl(N{{O}_{2}})]\]
C) \[[Co{{(N{{H}_{3}})}_{4}}(N{{O}_{2}})Cl][(N{{H}_{3}})Cl]\]
D) \[[Co{{(N{{H}_{3}})}_{5}}][{{(N{{O}_{2}})}_{2}}C{{l}_{2}}]\]
Correct Answer: A
Solution :
\[\because \] The complex gives three ions in aqueous solution \[\therefore \] The complex should be\[[Co{{(N{{H}_{3}})}_{5}}N{{O}_{2}}]C{{l}_{2}}\] It will give 3 ions on dissociation as follows: \[[Co{{(N{{H}_{3}})}_{5}}N{{O}_{2}}]C{{l}_{2}}\to CO{{(N{{H}_{3}})}_{5}}N{{O}_{3}}+2C{{l}^{-}}\]The chloride ions will give ppt. with\[AgN{{O}_{3}}\].You need to login to perform this action.
