Answer: The correct answer is Option B.
Explanation:
From the given options:
Option A: polar covalent bond
Polar covalent bond is defined as the bond which is formed when there is difference in electronegativity between the atoms forming a bond. For Example: HCl, the bond between the hydrogen and chloride element is a polar covalent bond.
Option B: dipole interaction
Dipole-dipole interactions are occured when partial charges are formed in one molecule and are attracted to the oppositely partial charge in a molecule which is present nearby. This bond is the weakest of all.
Option C: ionic bond
This bond is formed when a complete transfer of electrons takes place from one atom to another atom. Ions are formed during this reaction. Thus, this bond formed is the strongest.
The bond strength order follows:
[tex]\text{Ionic bond}>\text{Polar covalent bond}>\text{Dipole-dipole interactions}[/tex]
Hence, the correct answer is Option B.
