Final answer:
Organic compounds are covalently bonded molecules primarily composed of carbon and hydrogen. They can exhibit both potential and kinetic energy.
Step-by-step explanation:
Organic compounds are primarily composed of carbon and hydrogen, although other elements like oxygen, nitrogen, sulfur, and phosphorus may also be present in small amounts. They are usually covalently bonded molecules, which means the atoms are held together by shared electrons.
Organic compounds have a wide range of properties, including both potential and kinetic energy. Potential energy refers to the energy stored in the bonds between atoms, while kinetic energy refers to the energy associated with motion. Organic compounds can exhibit both potential and kinetic energy, making option III (potential and kinetic) the correct answer.
