Final answer:
The compounds that consist of molecules are d) CH₃(CH₂)₃OH and NF₃, as they are composed of nonmetals bonded covalently and do not include metals which would indicate an ionic compound.
Step-by-step explanation:
The compounds consisting of molecules among the provided options are CH₃(CH₂)₃OH and NF₃. Molecules are composed of nonmetals bonded covalently. Compounds LiOH, Ba(NO₃)₂, HNO₃, BaO, and Na₂O are considered ionic compounds because they are composed of metal cations and nonmetal anions. A compound like CH₃(CH₂)₃OH, which is butanol, consists solely of nonmetals carbon, hydrogen, and oxygen, so its atoms are held together by covalent bonds. Similarly, NF₃, nitrogen trifluoride, is composed of nitrogen and fluorine atoms, both nonmetals and is also a molecular compound with covalent bonds.
