Chemistry - Coordination Chemistry Question with Solution | TestHub

Given below are two statements, one is labelled as assertion$\mathbf{A}$and the other is labelled as Reason$\mathbf{R}$.
assertion$\mathbf{A}$:${\left[\mathrm{CoCl}{\left({\mathrm{NH}}_3\right)}_5\right]}^{2+}$absorbs at lower wavelength of light with respect to${\left[\mathrm{Co}{\left({\mathrm{NH}}_3\right)}_5\left({\mathrm{H}}_2\mathrm{O}\right)\right]}^{3+}$
Reason$\mathbf{R}$: It is because the wavelenght of light absorbed depends on the oxidation state of the metal ion.
In the light of the above statements,choose the correct answer from the options given below:
