Molecular geometry is the name of the geometric shape used to describe the shape of a molecule. The five molecular geometries are linear, trigonal planar, bent, tetrahedral, trigonal pyramidal, and seesaw.

When the electron pair and molecular geometry are different?

Electron pair geometry considers both bonding and lone pairs of electrons around a central atom, while molecular geometry focuses solely on the arrangement of bonded atoms. This can lead to different geometries when there are lone pairs present; for example, in ammonia (NH₃), the electron pair geometry is tetrahedral due to one lone pair, but the molecular geometry is trigonal pyramidal. The presence of lone pairs affects bond angles and the overall shape of the molecule, resulting in distinct geometries.

What is 5 electron domains?

In chemistry, 5 electron domains refer to the number of regions around an atom where electrons are likely to be found. This can correspond to a central atom surrounded by five bonding pairs or lone pairs of electrons. This configuration can result in different molecular geometries depending on the arrangement of these electron domains.

According to the vsepr theory what molecular geometries are associated with AB2?

The molecular geometry associated with AB2 molecules according to VSEPR theory is linear. This means that the two bonding pairs are arranged in a straight line with a bond angle of 180 degrees.


What structural feature is common to all geometric isomers?

Geometric isomers have different spatial arrangements around a double bond or a ring, leading to differences in their physical and chemical properties. This structural feature causes geometric isomers to have different geometries or shapes despite having the same molecular formula.
