VSEPR and IMF

Front

What does VSEPR stand for?

Back

Valence Shell Electron Pair Repulsion

Front

What is the basic principle of VSEPR theory?

Back

Molecules adopt shapes that minimize repulsion between electron pairs.

Front

What is the shape of a molecule with 2 bonding pairs and no lone pairs?

Back

Linear

Front

What is the shape of a molecule with 3 bonding pairs and 1 lone pair?

Back

Trigonal Pyramidal

Front

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

Back

Bent

Front

What intermolecular force is present in HF?

Back

Hydrogen Bonding

Front

What are London Dispersion Forces?

Back

Weak intermolecular forces arising from temporary dipoles in molecules.

Front

What are Dipole-Dipole Forces?

Back

Attractive forces between polar molecules due to their dipoles.

Front

Which molecule has the highest boiling point: H2, NH3, N2, O2?

Back

NH3 (Ammonia) due to hydrogen bonding.

Front

How do unshared pairs of electrons affect molecular shape?

Back

They repel bonding pairs, altering the shape of the molecule.
