Assertion (A) Linkage isomerism arises in coordination compounds containing ambidnetate ligand.
Reason (R) Ambidentate ligand has two different donor atoms.

Assertion Glycinate ion is an example of monodentate ligand Reason It contains N as the only donor atom .

Assertion (A) Among isomeric pentanes, 2, 2-dimethylpentane has highest boiling point. Reason (R ) Branching does not affect the boiling point.

(a). If both (A) and (R) are correct and (R) is the correct explanation for (A). (b). If both (A) and (R) are correct and (R) is not the correct explanation for (A). (c). If (A) is correct and (R) is incorrect. (d). If (A) is incorrect and (R) is correct. (e). If both (A) and (R) are incorrect. Q. Assertion (A): Dumas method is more applicable to nitrogen containing organic compounds than Kjeldahl's method. Reason (R): Kjeldahl's method does not give stisfactory results for compounds in which N is linked to O atom.

Assertion (A) . Sulphur present in an organic compound can be estimated quantitaively be Carius method. Reason (R). Sulpur is separated easily from other atoms in the molecule and gets precipitated as light yellow solid.

Write true or false: Ambidentate ligands can show linkage isomerism .

Name the type of isomerism when ambidentate ligands are attched to central metal ion. Give two examples of ambidentate ligands.

Assertion : N(CH_(2)CH_(2)NH_(2))_(3) and EDTA are examples of polydentate ligands . Reason : Ligands which can ligate through two different atoms is called polydentate ligand .

Assertion: In N_(2) Molecule, any N-atom can coordinate with central atom/ion. Reason: N_(2) molecule can also act as ambidentate ligand.

Assertion (A) Toxic metal ions are removed by the chelating ligands. Reason (R) Chelate complexes tend to be more stable.
