A hydrogen bond can occur between:
A. The two hydrogen atoms on a water molecule.
B. Two oxygen atom surrounded by hydrogens.
C. A hydrogen from one molecule and an oxygen from another molecule.
D. Two hydrogen atoms on different molecules.

Explanation:

Hydrogen bonding is a special type of dipole-dipole attraction between molecules, not a covalent bond to a hydrogen atom. It results from the attractive force between a hydrogen atom covalently bonded to a very electronegative atom such as a N, O, or F atom and another very electronegative atom.

The bonds between oxygen and the hydrogen atoms within the water molecule are polar covalent bonds,i.e., the electrons are not shared equally between oxygen and hydrogen. Oxygen has a higher affinity for electrons than does hydrogen

explanation:

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
