For each of the following molecules, provide a Lewis structure, including formal charge and resonance. Estimate ∆H°f for each of these molecules in the gas phase at 25°C.

ΔH°f (C(g)) = +717 kJ/mol DC-Cl = +330 kJ/mol DN=O = +607 kJ/mol

a) CH3OH (methanol)

b) COCl2 (phosgene) (Note: C is the central atom.)

c) H2NOH (hydroxylamine)

d) N2O4 (bonded like O2N-NO2)
