In the complex ‛[Co(NH3)6]3+”, which of the following best describes the ligand NH3?

easy MCQ 1 mark Class 11 · Biology · Chemical Coordination and Integration
  1. Monodentate, neutral
  2. Monodentate, anionic
  3. Bidentate, neutral
  4. Bidentate, anionic
Answer
Monodentate, neutral

The correct answer is Monodentate, neutral — Select the option that states "Monodentate, neutral".

Step-by-step solution

  1. Identify NH3 as a ligand in the complex.
  2. Determine its charge: NH3 is a neutral ligand.
  3. Determine its denticity: NH3 coordinates through one lone pair, hence monodentate.
  4. Select the option that states "Monodentate, neutral".
Common mistake: Treating NH3 as anionic

Concept tested: Ligand classification
