Understanding Bond Polarity and Electronegativity

What is the nature of sharing in covalent bonds?

• Always fair

• Always equal

• Not always entirely equal

• None of the above.

What is electronegativity?

• The measure of attraction for electrons in a bond

• The measure of repulsion for electrons in a bond

• The measure of attraction for protons in a bond

• The measure of repulsion for protons in a bond.

What does the acronym BEND stand for in determining if electron sharing is fair?

• A) Bond Electronegativity Difference

• B) Bond Energy Difference

What is a polar bond?

• A bond formed by equal sharing of electrons

• A bond formed by unequal sharing of electrons

• A bond formed by sharing of protons

• A bond formed by sharing of neutrons.

What is a polar bond?

• A bond where electrons are equally shared

• A bond where one atom pulls harder on shared electrons

• A bond with no shared electrons

• A bond with equal electronegativity.
