Question

The first step in drawing a Lewis electron-dot structure is to count the total number of valence electrons in the molecule. How many total

valence electrons are in the CH3Cl molecule?

A.16
B.10
C.12
D.14

Answer 1

14

Step-by-step explanation:

CH3Cl has 14 valence electrons. This is because:

Carbon is group 4 element, so it has 4 valence electrons

Hydrogen is group 1 element, so it has ony 1 valence electron

Cl (chlorine) is a halogen in group 7, thus 7 valence electrons.

Considering that there are 3 hydrogen atoms, the total number of valence electrons is 4 + 3*1 + 7 = 14
