The sulfamate ion, H2NSO3–, can be thought of as having been formed from the amide ion, NH2–, and sulphur trioxide, SO3.
(a) What are the electron-pair and molecular geometries or the amide ion and or SO3? What are the hybridizations of the N and S atoms, respectively?
(b) Sketch a structure for the sulfamate ion, and estimate the bond angles.
(c) What changes in hybridization do you expect for N and S in the course of the reaction
NH2– + SO3 → H2N—SO3–?
(d) Is SO3 the donor of an electron pair or the acceptor of an electron pair in the reaction with amide ion? Does the electrostatic potential map shown below confirm your prediction?
