Question

A molecule of ammonia (NH₃) has

Options

• only single bonds

• only double bonds

• only triple bonds

• two double bonds and one single bond

Answer 1

only single bonds

Explanation - 

Three hydrogen atoms share their electrons with one nitrogen atom to form a molecule of ammonia, NH₃. This allows nitrogen and hydrogen atom to attain the electronic configuration of the nearest noble gas Ne and He, respectively. The shared pair of electron is said to contribute a single covalent bond. So there are 3 single covalent bonds in ammonia.
