In the lewis structure for a molecule of methyl chloride, how many lone pairs of electrons does chlorine have when it is bonded with carbon A. 4
B. 0
C. 3
D. 2

Answer : The correct option is, (C) 3

Explanation :

Lewis-dot structure : It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule.

In the Lewis-dot structure the valance electrons are shown by 'dot'.

The given molecule is,

As we know that carbon has '4' valence electrons, hydrogen has '1' valence electron and chlorine has '7' valence electrons.

Therefore, the total number of valence electrons in = 4 + 3(1) + 7 = 14

According to Lewis-dot structure, there are 8 number of bonding electrons and 6 number of non-bonding electrons.

Hence, the number of lone pairs of electrons present on chlorine are, 3.
