Question

The number of shared pair of electrons present in an oxygen molecule and a methane molecule respectively are

Answer 1

Answer:

2of oxygen and 4 for methane

Answer 2

The number of shared pairs of electrons present in an oxygen molecule and a methane molecule is 2 pairs of electrons and 4 single pairs of electrons respectively.

• The number of shared pairs of electrons present in an oxygen molecule is 2 pairs. An oxygen atom has 6 electrons in its outermost orbit. Two atoms of oxygen in an oxygen molecule share two pairs of electrons by covalent bonding to complete their octet. This results in the formation of a double bond.
• The number of shared pairs of electrons present in a methane molecule is 4 single pair electrons. The single Carbon atom at the centre shares 4 electrons with each hydrogen atom.
