Final answer:
The compound CH2CH2 is classified both as a molecular compound due to its discrete molecules with covalent bonds, and as an organic compound because it contains carbon atoms bonded to hydrogen and other carbon atoms.
Step-by-step explanation:
The chemical compound CH2CH2, also known as ethylene or ethene, can be classified as both a molecular compound and an organic compound. It is a molecule because it consists of discrete molecules with covalent bonds between its atoms, and it's an organic compound because it contains carbon atoms bonded to hydrogen and other carbon atoms, which is the defining factor of organic chemistry. Ionic compounds, on the other hand, consist of a metal and a nonmetal ion that come together to form a crystal lattice, rather than discrete molecules like CH2CH2.
