In which of the following solvents are alkenes the more soluble?
- A
Water
- B
Ethyle alcohol
- C
Ammonia
- D
Carbon tetrachloride
We also know alkenes are non-polar, with negligible electronegativity difference between carbon and hydrogen and no difference between carbon and carbon.
So it will be more soluble in non-polar solvents.
Water is polar, and Oxygen is more electronegative than hydrogen, so alkenes being non-polar will not dissolve in water.
Ethyl alcohol is also polar, Oxygen is more electronegative than hydrogen, so alkenes being non-polar will not dissolve in ethyl alcohol.
Ammonia is also polar, nitrogen is more electronegative than hydrogen, so alkenes being non-polar will not dissolve in ammonia.
Carbon tetrachloride is non-polar In the carbon tetrachloride molecule, four chlorine atoms are positioned symmetrically as corners in a tetrahedral configuration joined to a central carbon atom by single covalent bonds. Because of this symmetric geometry, CCl4 is non-polar and alkenes are also nonpolar so they will get dissolved in it.
