Question

The degree of polarity of a chemical bond in a molecule of a compound can be predicted by determining the difference in the

(1) melting points of the elements in the compound
(2) densities of the elements in the compound
(3) electronegativities of the bonded atoms in a molecule of the compound
(4) atomic masses of the bonded atoms in a molecule of the compound

Answer 1

3

Step-by-step explanation:

bc The higher the difference in electronegativity the more the polar bond

Answer 2

(3) electronegativities of the bonded atoms in a molecule of the compound is the correct answer.

The compound is nonpolar when electronegativity is from 0 to 0.5, polar when electronegativity is from 0.5 to 1.7, and ionic when electronegativity is larger than 1.7.
