Question

Which of the following statements are correct?
(i) Square planar complexes of MABXL type show three isomers-two cis and one trans.
(ii) Complexes of $Ma _3 B _3$ type show three isomers-two cis and one trans.
(iii) Optical isomerism is common in octahedral complexes involving bidentate ligands.
(iv) $\left[ Co \left( NH _3\right)_4 Cl \left( NO _2\right)\right] Cl$ show linkage isomerism.

• A. (i), (ii) and(iii)
• B. (i), (iii) and (iv)
• C. (ii) and (iii)
• D. (iii) and (iv)

Answer 1

Answer: (B)

Complexes of $\left[ Ma _3 B _3\right]$ type shows fac- meridional isomerism.
Solvate isomerism is refered to as a hydrate isomerism when solvent is water.
