Polarity Practice

Front

What type of bond forms when Boron bonds with Hydrogen?

Back

nonpolar covalent

Front

Why is a diatomic molecule like O2 considered nonpolar?

Back

Because electrons are shared equally.

Front

In a polar covalent bond, how are electrons shared?

Back

Unequally.

Front

What is the molecular geometry of PH3?

Back

trigonal pyramidal

Front

What is the molecular geometry of H2S?

Back

bent

Front

Define a polar covalent bond.

Back

A bond where electrons are shared unequally between atoms with different electronegativities.

Front

What is the difference between polar and nonpolar molecules?

Back

Polar molecules have a net dipole moment due to unequal sharing of electrons, while nonpolar molecules do not.

Front

Give an example of a nonpolar molecule.

Back

O2 (oxygen gas) is a nonpolar molecule.

Front

What determines the polarity of a molecule?

Back

The difference in electronegativity between the bonded atoms and the molecular geometry.

Front

What is electronegativity?

Back

A measure of an atom's ability to attract and hold onto electrons.
