CHXII09:COORDINATION COMPOUNDS

321987 Which of the following can participate in linkage isomerism?

1

{NO}_{2}^{-}

2

H_{2} \ddot{{NCH}_{2}} {CH}_{2} \ddot{N} H_{2}

3

H_{2} O

4

: {NH}_{3}

Explanation:

${NO}_{2}^{-}$ may be bonded to metal through nitrogen (nitro) or through oxygen (nitrito). Hence ${NO}_{2}^{-}$ can participate in linkage isomerism.

CHXII09:COORDINATION COMPOUNDS

321988 Due to the presence of ambidentate ligands coordination compounds show isomerism. Palladium complexes of the type
$[Pd {(C_{6} H_{5})}_{2} (SCN)_{2}]$ and $[Pd {(C_{6} H_{5})}_{2} (NCS)_{2}]$ are

1 Linkage isomers

2 Coordination isomers

3 Ionisation isomers

4 Geometrical isomers

CHXII09:COORDINATION COMPOUNDS

321989 $[Cr {({NH}_{3})}_{6}] [Cr (SCN)_{6}]$ and $[Cr {({NH}_{3})}_{2} (SCN)_{4}] [Cr {({NH}_{3})}_{4} (SCN)_{2}]$ are the examples of what type of isomerism ?

CHXII09:COORDINATION COMPOUNDS

321990 Assertion :
$Co [Hg (SCN)_{6}]$ and $Hg [Co (SCN)_{6}]$ are isomers.
Reason :
${SCN}^{-}$ is a stronger ligand as compared to ${NCS}^{-}$ .

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 coordination compounds
$Co [Hg (SCN)_{4}]$ and $Hg [(CoSCN)_{4}]$ are
considered as ionization isomers. $SC \overset{―}{N}$ is
waeker ligand than $NC \overset{―}{S}$ . So the option (3) is correct.
