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 does VSEPR stand for?

Back

VSEPR stands for Valence Shell Electron Pair Repulsion, a theory used to predict the shape of molecules based on the repulsion between electron pairs.

Front

What is the primary purpose of VSEPR theory?

Back

The primary purpose of VSEPR theory is to predict the molecular shape of a molecule based on the number of electron pairs surrounding its central atom.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to form compounds in ways that give them eight valence electrons, achieving a stable electron configuration.

Front

What shape does a molecule with four bonding pairs and no lone pairs have?

Back

A molecule with four bonding pairs and no lone pairs has a Tetrahedral shape.

Front

What shape does a molecule with three bonding pairs and one lone pair have?

Back

A molecule with three bonding pairs and one lone pair has a Trigonal Pyramidal shape.

Front

What shape does a molecule with two bonding pairs and two lone pairs have?

Back

A molecule with two bonding pairs and two lone pairs has a Bent shape.

Front

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

Back

A molecule with two bonding pairs and no lone pairs has a Linear shape.

Front

How does the presence of lone pairs affect molecular geometry?

Back

Lone pairs repel more strongly than bonding pairs, which can alter the bond angles and overall shape of the molecule.

Front

What is the bond angle in a Trigonal Planar molecule?

Back

The bond angle in a Trigonal Planar molecule is approximately 120 degrees.
