Explanation / Answer

Generally, ionic bonds are formed between metals and nonmetals.Covalent bonds are formed between two nonmetals. C and N: covalent - both are nonmetals Na and Cl: ionic - Na is a metal and Cl is a nonmetal Al and C: ionic - Al is a metal and C is a nonmetal N and O: covalent - both are nonmetals Edit: I apologize. I believe Al and C are close enough inelectronegativity to result in a covalent bond.
