Chapter 1, Problem 45P

Consider another chemical species like the ones in the previous problems in which a carbon atom forms three single bonds to three hydrogen atoms but in which the carbon atom possesses a single unpaired electron. (a) What formal charge would the carbon atom have? (b) What total charge would the species have? (c) Given that the shape of this species is trigonal planar, what would you expect the hybridization state of the carbon atom to be?
