Polarity

Front

What determines the polarity of a bond?

Back

The difference in the electronegativities of the two atoms.

Front

Are polar molecules more likely to be solids and liquids than nonpolar molecules?

Back

True, so long as the nonpolar molecules are relatively small.

Front

In a polar covalent bond, where do the electrons gather?

Back

The atom with the Greatest Electronegativity.

Front

How do the Enthalpy of Fusion and Vaporization compare for polar molecules?

Back

They are higher for polar molecules due to stronger intermolecular forces.

Front

What type of molecule is O2 and why?

Back

O2 is nonpolar because electrons are shared equally.

Front

Define polarity in chemistry.

Back

Polarity refers to the distribution of electrical charge over the atoms joined by the bond.

Front

What is electronegativity?

Back

Electronegativity is the tendency of an atom to attract electrons towards itself.

Front

What is a polar covalent bond?

Back

A bond where electrons are shared unequally between two atoms.

Front

What is a nonpolar covalent bond?

Back

A bond where electrons are shared equally between two atoms.

Front

How do polar molecules interact with each other?

Back

Polar molecules exhibit stronger intermolecular forces due to their dipole moments.
