Which of the following bond has highest bond energy? A. O=O
B. H-CL
C. C=C
D. H-H

Ah , Bonds do be tougher to break in atoms than with friends.

Generally , the  smaller an atom is , the higher is it's bond energy. Therefore , Hydrogen atom is the smallest and therefore it contains the highest bond energy.

The Answer is option D.

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.
