[JEE MAIN Held on 08-01-2020 Evening]

(A) \[{{\left[ Pt{{\left( N{{H}_{3}} \right)}_{3}}Cl \right]}^{+}}\]

(B) \[{{\left[ Pt\left( N{{H}_{3}} \right)C{{l}_{5}} \right]}^{}}\]

(C) \[\left[ Pt{{\left( N{{H}_{3}} \right)}_{2}}Cl\left( N{{O}_{2}} \right) \right]\]

(D) \[{{\left[ Pt{{\left( N{{H}_{3}} \right)}_{4}}ClBr \right]}^{2+}}\]

A) (C) and (D)

B) (A) and (B)

C) (B) and (C)

D) (D) and (A)

Correct Answer: A

Solution :

\[\underset{\left( c \right)}{\mathop{\left[ Pt{{\left( N{{H}_{3}} \right)}_{2}}Cl\left( N{{O}_{2}} \right) \right]}}\,\text{ }and\text{ }\underset{\left( d \right)}{\mathop{{{\left[ Pt{{\left( N{{H}_{3}} \right)}_{4}}ClBr \right]}^{+2}}}}\,\] Can display geometrical isomerism
