Final answer:

Ionic and covalent bonds exist based on electrostatic attraction and electron sharing. Molecule II has both types of bonds between NaCl and NH4Cl, making choices II and IV the correct answers.


Explanation:

Ionic bonds result from the electrostatic attraction between ions of opposite charges, often involving a metal and a non-metal. Covalent bonds involve the sharing of electrons between atoms, typically between non-metals.

In the given options, molecule II contains both covalent and ionic bonds since it includes both NaCl (ionic) and NH4Cl (covalent).

Therefore, choices II, IV contain molecules with both covalent and ionic bonds.
