Question

Name the following

A molecule with two lone pairs and two bond pairs.

Answer 1

A lone pair of electron is the pair of electron that does not participate in bonding.

A bond pair of electron is the pair of electron that participates in the formation of covalent bond.

Answer:

The molecule that has two lone pair and two bond pair is water (${\mathrm{H}}_2\mathrm{O}$). The central atom in this molecule is Oxygen. Oxygen has 6 electrons in its valence shell, out of which 2 electrons take part in forming bond with Hydrogen.

So, 4 electrons are left, which forms the two lone pairs of electron. The molecule of water has a bent structure.
