图3. SO3的Lewis structure；可以画双键在任一个O上的其他共振式
Draw all of the Lewis structures of SeO3 that obey the octet rule and use this Lewis structure or these resonance structures to predict how many covalent bonds connect each oxygen atom in the real structure to the central Se atom. Assu...
Draw the Lewis structure for SO42- and state its molecular geometry. Is it polar or nonpolar? Draw the Lewis structure and write the molecular geometry and hybridization on the central atom, and polar or nonpolar for SeCl_6. Draw the Lewis structure for ...
Ab initio quantum chemical calculations, literature thermochemical studies in both gas and condensed phases, and simple chemical rules and regularities are used to show that SO 3 is a stronger Lewis acid than BF 3 . We show that this is due to the composite effect of relative bond strengths ...

This marked difference is due to SO3 being a much stronger Lewis acid (pF(-) value of 7.83) than SO2 (pF(-) value of 3.99), thus forming a stronger S-N bond with the Lewis base N-3(-). The geometry of the free gaseous SO2N3- anion was calculated at the RHF, MP2, B3LYP, ...
This ratio was be-lieved to be limited by the oxidative stability of the transi- tion-metal fragment, which functionsin these complexes as a Lewis base. We thank the CNPq (Brazil) for a grant to TMG C. The addition of two Ag⊕ ions to a basic metal center has been achieved by ...
The crystal structure of the title compound has been determined using three-dimensional X-ray diffraction data, from 839 reflections; crystals are orthorhombic, space group P212121, with unit-cell dimensions a= 9.405(1), b= 9.405(1), c= 12.321(1), Z= 4. The structure has been solved usi...
