What is the formal charge on an carbon atom with no lone pairs and 2 bonds?

The formal charge on 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 in carbon is 4 (since it is in the 4th group of the periodic table).

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

3. The number of bonding electrons is twice the number of bonds, since each bond consists of 2 electrons. So, for 2 bonds, there are 4 bonding electrons.

Substituting these values into the formula:

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

So, the formal charge on the carbon atom in this case is 2.
