When ammonia and hydrogen ion bond together to form ammonium ion, the bond formed is called

A.

ionic bond

B.

electrovalent bond

C.

covalent bond

D.

co-ordinate bond

E.

hydrogen bond

Correct answer is D

When one atom supplies both electrons in forming a two-electron bond, it is known as a dative covalent or coordinate bond. If two atoms contribute one electron each, it is known as a simple covalent bond. when ammonia and hydrogen ions bond together to form ammonium ion, the type of bond formed is a dative/coordinate covalent bond, because ammonia supplied both electrons with hydrogen contributing nothing.
