Re: VSEPR - T-shaped Molecules and Bond Angles Post by Chem_Mod » Fri Oct 23, 2015 9:40 am If both lone pairs occupied the axial positions (so that the bonded groups appear trigonal planar), there would be a total of 6 unfavorable 90-degrees interactions. allora, disegnata la tua molecola, generalmente riesci ad individuare un atomo centrale (a cui sono legati tutti gli altri) [nel caso di NH3 è N, CO2 è C H2O è O ecc]. It can asphyxiate by the displacement of air. We will use a model called the Valence Shell Electron-Pair Repulsion (VSEPR) model that is based on the repulsive behavior of electron-pairs. This produces a set of geometries which depend only on the number of valence shell electron pairs and not on the atoms present. If none of the clouds is a lone pair, the molecular geometry will also be trigonal planar. Here, the fluxional nature of the CH 3 subunits and a three-center-two-electron (3c-2e) bonded H 2.
