Oxygen molecule, geometry, transition

VSEPR should be able to predict the geometry around any atom in a complex molecule, where main-group atoms are involved (It can not be generally applied to transition metals), e.g, in NH2OH, the bonds around the nitrogen are pyramidal and those around oxygen bent as expected. [Pg.191]

The geometry of this transition state can be described as a methenium carbocation sandwiched in between a benzene molecule and a deprotonated Bn0nsted site. The methenium ion is planar, and its carbon atom is located along the line defined by the zeolitic oxygen atom to which it will be bonded and the aromatic carbon atom to which it was bonded. The activation energy which is required to achieve this reaction is act = + 279 kJ/mol. [Pg.13]
