Whats the total number of bonding electrons for CH3F? Whats the total number of nonbonding electrons for CH3F?
This site does not allow us to draw diagrams (or anything else) but here is a link that will how you the electron dot structure for CH3F. You can count the number of bonding and non-bonding electrons.
Hello DrBob, I do not think you have added the link to the website.
Sorry about that.That's a common mistake of mine.

To find the total number of bonding electrons for CH3F, we need to determine the Lewis structure for the molecule. Here's how to do it:
1. Count the total number of valence electrons for each atom. Carbon (C) has 4 valence electrons, Hydrogen (H) has 1 valence electron, and Fluorine (F) has 7 valence electrons.
- Carbon (C): 4 valence electrons
- Hydrogen (H): 1 valence electron
- Fluorine (F): 7 valence electrons
2. Calculate the total number of valence electrons for the molecule by adding up the valence electrons of each atom:
- Carbon (C): 4 valence electrons
- Hydrogen (H): 3 valence electrons
- Fluorine (F): 7 valence electrons
Total: 4 + 3 + 7 = 14 valence electrons
3. Determine the least electronegative atom, which is Carbon (C), to be the central atom. Hydrogen (H) atoms are generally not the central atom.
4. Connect the central atom (carbon) to the other atoms (hydrogen and fluorine) using single bonds (each single bond represents two electrons).
- Carbon (C): 4 valence electrons, needs 4 more to complete octet.
- Hydrogen (H): 1 valence electron, needs 1 more to complete its duet.
- Fluorine (F): 7 valence electrons, needs 1 more to complete octet.
Here's the Lewis structure for CH3F:
H F

H - C - F
5. Distribute the remaining valence electrons (14 - 8 = 6) as lone pairs on the outer atoms (hydrogen and fluorine) to satisfy the octet rule.
- Carbon (C): 4 valence electrons
- Hydrogen (H): 0 valence electron (as lone pair)
- Fluorine (F): 2 valence electrons (as lone pair)
The Lewis structure for CH3F now looks like this:
H F
| |
H - C - F
In this structure, there is a carbon-hydrogen (C-H) bond and a carbon-fluorine (C-F) bond. Each bond represents two electrons, so the total number of bonding electrons can be calculated by multiplying the number of bonds by 2. In CH3F, there are three bonds (C-H, C-F, and C-F), so:
Total number of bonding electrons = 3 bonds * 2 electrons/bond = 6 electrons.
Regarding the total number of nonbonding electrons, it refers to the lone pairs of electrons on the outer atoms. In the Lewis structure of CH3F, there are 2 lone pairs of electrons on the fluorine atom.
Therefore, the total number of nonbonding electrons for CH3F is 2 electrons.
