If a molecule demonstrates paramagnetism, then:
1. The substance can have both paired and unpaired electrons.
II. The bond order is not a whole number.
III. It can be determined by drawing a Lewis structure.
IV. It must be an ion.

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."
