Answer:
Covalent bonds are stronger than ionic bonds
Explanation:
Ionic bonds are formed by the transfer of electrons from the electropositive element to the electronegative element. Covalent bonds are formed by the mutual sharing of electrons.
Covalent bonds have high bond dissociation energy as compared to the ionic bond. The overlapping of molecular orbital is bigger in case of covalent bond as compared with ionic bonds. Hence, covalents bonds are difficult to break and stronger than ionic bonds.
Thus, the correct answer is option (D).
