Statement 1: Azeotropes are the mixtures of refrigerants and behave like pure substances.
An azeotrope is a mixture of two or more substances that has a constant boiling point and composition. In the context of refrigerants, azeotropes are commonly used as working fluids in refrigeration and air conditioning systems. When an azeotropic mixture is boiled, the vapor produced has the same composition as the liquid. This means that during the phase change, the composition of the mixture remains constant.

Statement 2: Isomers refrigerants are compounds with the same chemical formula but have different molecular structures.
Isomers are compounds that have the same molecular formula but different structural arrangements or spatial orientations of their atoms. In the case of refrigerants, isomers can have the same chemical formula but differ in terms of how their atoms are bonded together. This can lead to differences in properties such as boiling points, stability, and reactivity.

Statement 3: The formula n p q = 2m is used for unsaturated chlorofluorocarbon compounds (m, n, p, and q are the numbers of atoms of carbon, hydrogen, fluorine, and chlorine respectively).
The formula n p q = 2m represents a relationship between the numbers of carbon, hydrogen, fluorine, and chlorine atoms in unsaturated chlorofluorocarbon compounds. The formula suggests that for every two carbon atoms, there must be one hydrogen atom, one fluorine atom, and one chlorine atom. This formula helps to determine the molecular formula of unsaturated chlorofluorocarbons based on the number of atoms of each element.

Correct Answer: Option D - 1, 2, and 3
All three statements are correct. Azeotropes are indeed mixtures of refrigerants that behave like pure substances, isomers refrigerants have the same chemical formula but different molecular structures, and the formula n p q = 2m is used for unsaturated chlorofluorocarbon compounds.
