1.43 consider a chemical species (either a molecule or an ion) in which a carbon atom forms three single bonds to three hydrogen atoms and in which the carbon atom possesses no other valence electrons. (a) what formal charge would the carbon atom have? (b) what total charge would the species have? (c) what shape would you expect this species to have? (d) what would you expect the hybridization state of the carbon atom to be?
