Why is the molecule polar?

• There is a nonbonding pair on the central atom.

• There are different types of elements bonded to the central atom.

• There are no nonbonding pairs on the central atom and all of the atoms bonded to the central atom are the same.

If carbon forms a covalent bond with chlorine, which end of the bond will be partially negative?

• the carbon end

• the chlorine end

Which of the following correctly compares polar covalent and nonpolar covalent bonding?

• Polar covalent bonds share the valence electrons equally but the nonpolar covalent bond is shared unequally.

• Polar covalent bonds share the valence electrons unequally but the nonpolar covalent bond is shared equally.

• Polar covalent bonds create a symmetrical electron density around each nucleus in the bond but nonpolar covalent bonds create asymmetrical electron density.

• Nonpolar covalent bonds involved hydrogen bonded to another nonmetal and polar covalent is two identical nonmetals.
