Molecular Geo, Polarity and IMFs

Front

What are the strongest to weakest intermolecular forces (IMFs)?

Back

Hydrogen Bond, Dipole-dipole, London Dispersion.

Front

What effect does a strong IMF have on boiling point?

Back

A strong IMF increases the boiling point.

Front

In an electron dot diagram, what does two pairs of shared electrons represent?

Back

Double bond.

Front

Which type of intermolecular force has the strongest attraction?

Back

Hydrogen Bonds.

Front

What is the correct structure for ammonia?

Back

Option C.

Front

Define intermolecular forces (IMFs).

Back

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

Front

What is a hydrogen bond?

Back

A strong type of dipole-dipole attraction that occurs between molecules containing hydrogen bonded to highly electronegative atoms like N, O, or F.

Front

What is a dipole-dipole interaction?

Back

An attractive force between the positive end of one polar molecule and the negative end of another polar molecule.

Front

What are London dispersion forces?

Back

Weak intermolecular forces that arise from temporary shifts in electron density in nonpolar molecules.

Front

How do IMFs affect solubility?

Back

Stronger IMFs can increase solubility in polar solvents.
