What determines the molecular geometry of a molecule?
Consider: Number of bonding domains on the central atom Number of non-bonding electron pairs (lone pairs) on the central atom
The hybridization of the valence electrons on the carbon atom in CO2 is The electron pair geometry is and the shape of the molecule is?
sp, linear, linear
What is the difference between the arrangement of electron pairs and the shape of the molecules?
The shape of a molecule only describes the arrangement of bonds around a central atom. The arrangement of electron pairs describes how both the bonding and nonbonding electron pair are arranged. For example, in its molecular shape, a water molecule is describes as bent, with two hydrogen atoms bonded to an oxygen atom. However, the arrangement of electron pairs around the oxygen atom is tetrahedral as there are two bonding pairs (shared with the hydrogen) and also two nonbonding pairs.
What is the most important factor determining the geometry of a molecule or an ion?
The geometry of the molecule actually determines number of electron pairs on the central atom. The electron pairs will be arranged in such a way to minimize the repulsion and therefore, have the lowest possible energy.
What is the molecular geometry of a molecule with 5 outer atoms and 1 lone pair on the central atom?
Anything with six electron groups, keep in mind an electron group is a bonded atom or an electron pair, is an octahedral. Anything in an octahedral and a lone pair is the square pyramidal geometry. So all angles between the atoms are a little less than 90 degrees and the angle of the electron pair is greater than 90.
