Question

[Co(NH₃)4Cl₂]NO₂ and [Co(NH₃)₄Cl(NO₂)]Cl are ______.

Options

• geometrical isomers

• optical isomers

• linkage isomers

• ionisation isomers

Answer 1

[Co(NH₃)4Cl₂]NO₂ and [Co(NH₃)₄Cl(NO₂)]Cl are ionisation isomers.

Explanation:

The compounds [Co(NH₃)4Cl₂]NO₂ and [Co(NH₃)₄Cl(NO₂)]Cl are ionisation isomers, as they have the same composition but differ in the counter ions: \[\ce{NO^{-}_2}\] in one and Cl⁻ in the other.
