Electronegativity and Bonding

A diatomic molecule like O₂ is always_______ because electrons are shared ________.

• nonpolar; equally

• polar; equally

• nonpolar; unequally

• nonpolar; unequally

If the difference in electronegativity is 0.2, the bond is ________.

• polar covalent

• nonpolar covalent

• ionic

The polarity of a bond is determined by...

• The sum of the electronegativities of the two atoms

• The difference in the electronegativities of the two atoms

• The charges of the atoms

• The number of electrons shared in the bond

Which of the following statements correctly explains why hydrogen bonding is such a strong intermolecular force?

• There is an attraction between a small, weakly electronegative hydrogen atom and a large, strongly electronegative atom of fluorine, nitrogen, or oxygen

• There is an attraction between a small, highly electronegative hydrogen atom and a large, highly electronegative fluorine atom

• There is an attraction between the hydrogen and oxygen atoms, only

• There is an attraction between the hydrogen and nitrogen atoms, only
