The metallic bond is non-directional.

8) H-bonds are stronger than

A. Ionic bonds

B. Metallic bonds

C. Covalent bonds

D. Van der Waals bonds

Correct Answer is "D"

H-bonds are stronger than Van der waals bonds.

9) If the radius of cation is r₊ and that of anion is r_- what will be the bond length
