Front

What is the shape of a molecule with 4 bonded atoms around the central atom?

Back

Tetrahedral

Front

What is the definition of a polar molecule?

Back

A polar molecule has a net dipole moment due to the presence of polar bonds that do not cancel each other out.

Front

Does H2O have hydrogen bonding?

Back

Yes

Front

What is the bond angle in a tetrahedral molecular shape?

Back

Approximately 109.5 degrees.

Front

In a polar covalent bond, electrons are shared ___________.

Back

unequally

Front

What is the shape of a molecule with 3 bonded atoms and 1 lone pair?

Back

Pyramidal

Front

What is the definition of a non-polar molecule?

Back

A non-polar molecule has no net dipole moment, often due to symmetrical distribution of charge.

Front

What is the shape of a molecule with 2 bonded atoms and 0 lone pairs?

Back

Linear

Front

What type of bond forms between two non-metals with similar electronegativities?

Back

Non-polar covalent bond.
