Question

Table 2:

3) The polarity of a molecule is a consequence of its structure and is one of the determinants of the physical and chemical characteristics exhibited by the molecule. If you have ever observed a bottle of oil and vinegar salad dressing before shaking it you have observed one of the consequences of the polarity of molecules, "like dissolves like” and consequently "oil and water don't mix”. (It is important to point out here that vinegar is 95% water and 5% acetic acid.) The oil floats on top of the vinegar because it is less dense than the vinegar but also because oil molecules are non-polar and water is a polar molecule. Given this background: a) Which fluorinated molecule in Table 2 is MOST likely able to mix with water. b) Why?

Answer 1

Among the given fluorinated molecules CHF3 is most soluble in water. CHF3 and water are soluble because they are both polar molecules. CHF3 has more dipole-moment than other given fluorinated molecules.
