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.

What is a lone pair in molecular geometry?

Back

A lone pair is a pair of valence electrons that are not shared with another atom and are not involved in bonding.

Front

How does the presence of lone pairs affect molecular shape?

Back

Lone pairs occupy space and can repel bonding pairs of electrons, altering the molecular shape compared to a molecule with only bonding pairs.

Front

What is the VSEPR theory?

Back

Valence Shell Electron Pair Repulsion (VSEPR) theory is a model used to predict the geometry of individual molecules based on the repulsion between electron pairs.

Front

What molecular shape is formed by 2 bonding pairs and 1 lone pair?

Back

The molecular shape is Trigonal Pyramidal.

Front

What is the molecular shape of a molecule with 4 bonding pairs and no lone pairs?

Back

The molecular shape is Tetrahedral.

Front

What is the central atom in a molecule?

Back

The central atom is the atom in a molecule that is bonded to other atoms and typically has the highest valence.

Front

What is the molecular shape of a molecule with 2 bonding pairs and 2 lone pairs?

Back

The molecular shape is Bent.

Front

How many electron groups are present in a molecule with 3 bonds and 1 lone pair?

Back

There are 4 electron groups (3 bonding pairs + 1 lone pair).

Front

What is the molecular shape of a molecule with 3 bonding pairs and no lone pairs?

Back

The molecular shape is Trigonal Planar.
