Consider the following statements:
1. Azeotropes are the mixtures of refrigerants and behave like pure substances.
2. Isomers refrigerants are compounds with the same chemical formula but have different molecular structures.
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)
Which of the statements are correct?
Option (A)
1 and 3
Option (B)
2 and 3
1 and 2
1, 2 and 3
Correct Option:
Question Solution:
But for unsaturated hydrogen
2m = p + q + n
So 3 is correct
