Question

Donations of electron from what. 1 covalent 2 electron valent 3 coordinate covalent​

Answer 1

Answer:

Explanation:

In a coordinate covalent bond, the electrons are conceived to be supplied by the ONE atom............

Consider the acid-base behaviour of ammonia:

H3N(aq)+H2O(l)⇌NH+4+HO−

The lone pair on ammonia is conceived to donate electrons to form a coordinate covalent bond with the proton. Of course in ammonium ion,

NH+4, all of the N−H

bonds are equivalent, but nitrogen has a formal positive charge because its lone pair has been donated to H+.
