CHXII09:COORDINATION COMPOUNDS

321982 Which one of the following complexes exhibit chirality?

1

{[Cr (ox)_{3}]}^{3 -}

2 cis-

[{PtCl}_{2} {({NH}_{3})}_{2}]

3

{[Pt {({NH}_{3})}_{4}]}^{2 +}

4

mer - [Co {({NO}_{2})}_{3} (

trien

)]

Explanation:

${[Cr (o x)_{3}]}^{3 -}$ shows optical isomerism.

CHXII09:COORDINATION COMPOUNDS

321983 Assertion :
$[Co {({NO}_{2})}_{3} {({NH}_{3})}_{3}]$ does not show optical isomerism.
Reason :
It has a plane of symmetry.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.

2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.

3 Assertion is correct but Reason is incorrect.

4 Assertion is incorrect but Reason is correct.

Explanation:

The essential requirement for a substance to exhibit optical activity is the absence of a plane of symmetry within its molecular or structural arrangement. In the given structure of $[Co {({NO}_{2})}_{3} {({NH}_{3})}_{3}]$ , there is a plane of symmetry that makes the complex optically inactive. So the option (1) is correct.

CHXII09:COORDINATION COMPOUNDS

321984 Which can exist both as diastereoisomer and enantiomer?

{[Pt (en)_{2} ClBr]}^{2 +}

3

{[Ru {({NH}_{3})}_{4} {Cl}_{2}]}^{0}
