Question: Which compound has the weakest bond?

a. Diamond
b. Neon (solid)
c. KCl
d. Water (ice)

Answer:
Answer: (b)

Diamond contains strong covalent bonds. In potassium chloride (KCl), an ionic bond is present whereas in ice molecules, a hydrogen bond is present. Neon solids are usually held together by Van Der Waals forces.

Decreasing order of strength of bond is as follows:-

Ionic > Covalent > Hydrogen > Dipole−Dipole > Van der Waals
