Chem '24-'25 Semester 1 Review

Front

What is the molecular geometry of water (H₂O)?

Back

Bent

Front

If there are lone pairs on the central atom, what is the molecular polarity?

Back

Polar

Front

What type of intermolecular force (IMF) do nonpolar molecules only have?

Back

London Dispersion Forces (LDF)

Front

Which intermolecular force is the strongest among London dispersion forces, dipole-dipole forces, hydrogen bonding, and ionic forces?

Back

Hydrogen bonding

Front

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

Back

Trigonal pyramidal

Front

Define molecular geometry.

Back

The three-dimensional arrangement of atoms in a molecule.

Front

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

Back

Lone pairs repel more strongly than bond pairs, affecting the overall geometry.

Front

What is the difference between polar and nonpolar molecules?

Back

Polar molecules have an uneven distribution of charge, while nonpolar molecules have an even distribution.

Front

What are intermolecular forces (IMF)?

Back

Forces of attraction or repulsion between neighboring particles (atoms, molecules, or ions).

Front

List the types of intermolecular forces from weakest to strongest.

Back

London dispersion forces, dipole-dipole forces, hydrogen bonding, ionic forces.
