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, [tex]CH_3Cl[/tex]
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 [tex]CH_3Cl[/tex] = 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.
