Question

Both geometrical and optical isomerisms are shown by

(a) \(\left[\mathrm{Co}(\text { en })_{2} \mathrm{Cl}_{2}\right]^{+}\)

(b) \(\left[\mathrm{Co}\left(\mathrm{NH}_{3}\right)_{5} \mathrm{Cl}\right]^{2+}\)

(c) \(\left[\mathrm{Co}\left(\mathrm{NH}_{3}\right)_{4} \mathrm{Cl}_{2}\right]^{+}\)

(d) \(\left[\mathrm{Cr}(o x)_{3}\right]^{3-}\)

Answer 1

Correct option is (a) \(\left[\mathrm{Co}(\text { en })_{2} \mathrm{Cl}_{2}\right]^{+}\)

Both geometrical and optical isomerism is shown by [Co(en)₂Cl₂]⁺.

No isomerism is shown by [Co(NH₃)₅Cl]²⁺.

[Co(NH₃)₄Cl₂]⁺ shows geometrical isomerism.

[Cr(ox)₃]^3- shows optical isomerism.
