Generally, a group of atoms can function as a ligand if
They are positively charged ions
They are free radicals
They are either neutral molecules or negatively charged ions
None of these
As we have learned
Types of Ligands on the basis of charge -
There are 3 types
- wherein
(i) Neutral - having No charge but lone pair
eg:
(ii) Negative charged - having -ve charge
eg:
(iii) Positive charge - having +ve charge but are very less
eg:
Ligand must have capacity to donate lone pair of electrons to form co-ordinate bond.
