What is the formal charge on an carbon atom with no lone pairs and 4 bonds?

The formal charge of an atom can be calculated using the formula:

Formal Charge = Valence Electrons - (Non-bonding electrons + 1/2 Bonding electrons)

For a carbon atom:

1. The number of valence electrons is 4 (as carbon is in the 4th group of the periodic table).

2. Since there are no lone pairs, the number of non-bonding electrons is 0.

3. The number of bonding electrons is 8 (as each bond consists of 2 electrons and there are 4 bonds).

Substituting these values into the formula:

Formal Charge = 4 - (0 + 1/2 * 8) = 4 - 4 = 0

So, the formal charge on a carbon atom with no lone pairs and 4 bonds is 0.
