Questions
  1. Statement is true
    Yes
    Statement
    An ambidentate ligand has two different possible donor atoms.
  2. Statement is true
    Yes
    Statement
    NO₂⁻ can bind through nitrogen or through oxygen.
  3. Statement is true
    Yes
    Statement
    SCN⁻ can bind through sulphur or through nitrogen.
  4. Statement is true
    No
    Statement
    An ambidentate ligand uses both donor atoms at once.
  5. Statement is true
    Yes
    Statement
    A chelate ligand uses two or more donor atoms simultaneously.
An ambidentate ligand has two DIFFERENT donor atoms and uses only one of them at a time, which is what separates it from a chelate. Source: syllabus Chemistry Part I, Ch 5 Coordination Compounds.

Categories
  1. Item
    Chelate
  2. Item
    Ambidentate
Both involve more than one candidate donor atom, but a chelate uses them together while an ambidentate ligand picks one. Source: syllabus Chemistry Part I, Ch 5 Coordination Compounds.
