A ligand can be

A

a neutral molecule with lone pair of electrons

B

a neutral atom with lone pair of electrons

C

a negative ion with lone pair of electrons

D

a positive ion with lone pair of electrons.

Text Solution

Verified by Experts

The correct Answer is:
A, C, D
A ligand can be a neutral molecule, negative ion or a positive ion, but it mout have one or more lone pairs of electrons . No neutral atom acts as a ligand.

Which of the following ligands can exhibit linkage isomerism ?

Read the passage given below and answer the following questions : According to Valence Bond Theory, the metal atom or ion under the influence of ligands can use its (n-1)d, ns, np or ns, np, nd orbitals for hybridisation to yield a set of equivalent orbitals of definite geometry such as octahedral, tetrahedral, square planar and so on. These hybridised orbitals ar allowed to overlap with ligand rbitals that can donate electron pairs for bonding. Assertion (A) : In the diamagnetic octahedral complex, [Co(NH_(3))_(6)]^(3+) , the cobalt ion is in +3 oxidation state. Reason (R) : Six pairs of electrons, one from each NH_(3) molecule, occupy the six hybrid orbitals.

These hybridised orbitals ar allowed to overlap with ligand rbitals that can donate electron pairs for bonding. Assertion (A) : In the square planar complexes, the hybridisation involved is dsp^(2) . Reason (R) : In [NiCl)_(4)]^(2-) . Here nickel is in +2 oxidation state and has the electronic configuration 3d^(8) .

Read the passage given below and answer the following questions : According to Valence Bond Theory, the metal atom or ion under the influence of ligands can use its (n-1)d, ns, np or ns, np, nd orbitals for hybridisation to yield a set of equivalent orbitals of definite geometry such as octahedral, tetrahedral, square planar and so on. These hybridised orbitals ar allowed to overlap with ligand rbitals that can donate electron pairs for bonding. Assertion (A) : [NiCl_(4)]^(2-) is an inner orbital complex. Reason (R) : An inner orbital or low spin or spin paired complex uses inner d orbitals of the metal ion for hybridisation.
