Front

Arrange the following in order of increasing boiling point: CH4, NH3, HF, H2O.

Back

CH4 < NH3 < HF < H2O.

Front

What is the order of boiling points for simple molecular structures: Ar, Cl, P, S?

Back

Ar < Cl < P < S.

Front

If element L has 2 valence electrons and M has 1 valence electron, what can be inferred about their boiling points?

Back

L has a higher boiling point and melting point than M.

Front

What type of bond is formed between metal atoms?

Back

Metallic bond.

Front

What is the significance of valence electrons in determining the strength of metallic bonds?

Back

More valence electrons typically lead to stronger metallic bonds.

Front

How do intermolecular forces affect boiling points of substances?

Back

Stronger intermolecular forces result in higher boiling points.

Front

What are the main types of intermolecular forces?

Back

Dipole-dipole interactions, hydrogen bonding, and London dispersion forces.

Front

What is hydrogen bonding and why is it significant?

Back

Hydrogen bonding is a strong type of dipole-dipole interaction that occurs when hydrogen is bonded to highly electronegative atoms like N, O, or F.
