What is the formal charge on an carbon atom with no lone pairs and 1 bonds?

You haven't provided any text for me to respond to. Could you please provide the text?

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

Formal Charge = [# of valence electrons on atom] - [non-bonding electrons + number of bonds]

Carbon has 4 valence electrons. In this case, the carbon atom has no lone pairs (non-bonding electrons) and 1 bond.

So, the formal charge on the carbon atom would be:

Formal Charge = 4 - (0 + 1) = 3

Therefore, the formal charge on the carbon atom in this case is +3.
