Final answer:
The relationship between propane and propan-2-ol is designated by the term propan-2-ol. Propan-2-ol is an alcohol derived from propane by substituting one of the hydrogen atoms with a hydroxy (-OH) group.
Step-by-step explanation:
The relationship between propane and propan-2-ol is designated by the term propan-2-ol. Propane is a hydrocarbon with the chemical formula C3H8, while propan-2-ol is an alcohol with the chemical formula C3H8O. Propan-2-ol is derived from propane by substituting one of the hydrogen atoms with a hydroxy (-OH) group. This substitution changes the chemical properties of the compound, making it an alcohol.
