In Section 5.6, we learned that triple bonds are stronger and shorter than single bonds. For example, a C−CC−C single bond has an average bond energy of 347 kJ/molekJ/mole, while a C≡CC≡C triple bond has an average bond energy of 837 kJ/molekJ/mole. Use valence bond theory to explain why a triple bond is not simply three times as strong as a single bond.

the strength of a bond depends on the amount of overlap between the atoms.

Explanation:the greater the overlap the greater the strength of the bond.

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.
