Verified step by step guidance1
Understand the definition of an organic compound: Organic compounds are primarily made of carbon atoms bonded to hydrogen atoms, and they may also contain other elements such as oxygen, nitrogen, sulfur, and halogens.
Examine each compound to determine if it fits the definition of an organic compound.
Analyze CaCO3: This compound is calcium carbonate, which is an inorganic compound because it consists of a metal (calcium) and a carbonate group, not primarily carbon and hydrogen.
Analyze C4H8: This compound is composed of carbon and hydrogen atoms only, fitting the definition of an organic compound. It is an alkene, specifically butene, which is a hydrocarbon.
Analyze LiF and CaO: LiF is lithium fluoride, an ionic compound made of a metal and a halogen, and CaO is calcium oxide, an ionic compound made of a metal and oxygen. Both are inorganic compounds.
