AP Chemistry Thou Shall Not Forget- Part 1

Front

List the 3 Intermolecular forces from weakest to strongest.

Back

London dispersion, dipole-dipole, hydrogen bonding.

Front

What is the bond angle in BF3?

Back

120 degrees.

Front

When an electron is in a lower energy level, it is ________________ away from the nucleus.

Back

Closer.

Front

Real gases behave most like an ideal gas at what conditions of temperature and pressure?

Back

High temperature, low pressure.

Front

When an electron is in a lower energy level, it has a ________________ 1st ionization energy.

Back

Higher.

Front

Define intermolecular forces.

Back

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

Front

What is the shape of BF3 and why?

Back

Trigonal planar due to three bonding pairs and no lone pairs on the central atom.

Front

Explain the concept of ionization energy.

Back

The energy required to remove an electron from an atom or ion.

Front

What is the trend of ionization energy across a period?

Back

Ionization energy generally increases across a period due to increasing nuclear charge.

Front

What is the trend of ionization energy down a group?

Back

Ionization energy generally decreases down a group due to increased distance from the nucleus.
