VSEPR and molecular compounds

Front

What is VSEPR theory?

Back

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

What is the molecular shape of a molecule with 3 bonded atoms and 1 lone pair on the central atom?

Back

The molecular shape is trigonal pyramidal.

Front

What is the molecular shape of a molecule with 4 bonded atoms and no lone pairs on the central atom?

Back

The molecular shape is tetrahedral.

Front

What is the molecular shape of a molecule with 2 bonded atoms and 2 lone pairs on the central atom?

Back

The molecular shape is bent.

Front

What is the molecular shape of a molecule with 2 bonded atoms and no lone pairs on the central atom?

Back

The molecular shape is linear.

Front

What type of bonds do molecular compounds have?

Back

Molecular compounds have covalent bonds.

Front

Can molecular compounds be polar or non-polar?

Back

Yes, molecular compounds can be either polar or non-polar.

Front

What is a polar molecule?

Back

A polar molecule is a molecule that has a net dipole moment due to the presence of polar bonds and an asymmetrical shape.

Front

What is a non-polar molecule?

Back

A non-polar molecule is a molecule that does not have a net dipole moment, often due to symmetrical shape or equal sharing of electrons.

Front

What is the significance of lone pairs in determining molecular shape?

Back

Lone pairs occupy space and repel bonded pairs, affecting the overall geometry of the molecule.
