Question

1. NH3 is a good complexing agent explain? ​

Answer 1

As there is a lone pair of electrons the ammonia molecule has a good tendency to donate electrons. ... Thus, as ammonia has a good tendency to donate electrons, it has a good ability to form stable complexes. Thus, ammonia is a good complexing agent.

Answer 2

Answer:

Ammonia is a good complexing agent because it is a good lewis base. The lone pair of electrons on N atom can be easily donated to central metal.

For example, in the complex [Ag(NH

3

)

2

]Cl, two ammonia ligands form a complex with Ag by donating lone pair of electrons on N atom to form coordinate bond.
