What is Molecular Geometry?

Back

Molecular Geometry refers to the three-dimensional arrangement of atoms within a molecule, which influences its physical and chemical properties.

Front

What determines the shape of a molecule?

Back

The shape of a molecule is determined by the number of bonding pairs and lone pairs of electrons around the central atom, as described by VSEPR (Valence Shell Electron Pair Repulsion) theory.

Front

Define a lone pair.

Back

A lone pair is a pair of non-bonding electrons that are localized on a single atom and not shared with another atom.

Front

What is the shape of a molecule with four bonding pairs and no lone pairs?

Back

Tetrahedral.

Front

What is the shape of a molecule with three bonding pairs and one lone pair?

Back

Trigonal Pyramidal.

Front

What is the shape of a molecule with two bonding pairs and two lone pairs?

Back

Bent.

Front

What is the shape of a molecule with two bonding pairs and no lone pairs?

Back

Linear.

Front

What is the shape of a molecule with five bonding pairs?

Back

Trigonal Bipyramidal.

Front

What is the shape of a molecule with three bonding pairs and no lone pairs?

Back

Trigonal Planar.

Front

How does a lone pair affect molecular geometry?

Back

A lone pair occupies space and repels bonding pairs, which can alter the expected geometry of the molecule.
