Question

in terms of bond strength, which of the following is the weakest?
○ covalent and hydrogen
○ ionic
○ covalent
○ hydrogen
○ bonds cannot be strong or weak.

Explanation:

To determine the weakest bond, we analyze the types: Covalent bonds involve electron sharing (strong), ionic bonds involve ion attraction (strong), and hydrogen bonds are intermolecular attractions (weaker than covalent/ionic). The option "covalent and hydrogen" is a mix, "ionic" and "covalent" are strong, "Bonds cannot be strong or weak" is incorrect. So hydrogen bonds are the weakest.

Answer:

D. hydrogen
