Explanation / Answer

b. Non-polar compounds are least soluble in water. They are soluble in organic solvents. In the given option, hexane is most non-polar compound, having a long alkyl chain. So hexane will be least soluble in water followed by cyclohexanol. It has -OH group with a benzene ring, so it will be more soluble than hexane. Out of ethanol and ethan-1,2 diol, ethan-1,2 diol has greater solubility because of two OH groups. So order of solubility will be

Ethan-1,2-dio> Ethanol> Cyclohexanol> hexane

c. 2,2-difluoro propanol is more acidic as fluorine is more electronegativity than chlorine. Greater the electronegativity, more will be the acidic character.and propan-1-ol will be least acidic as it does not have any electronegative element attached to it. Out of 2 and 3-propanol, 2-propanol is more acidic as it has Cl attached to OH atom. so the rank of acidity is;

2,2-difluoropropan-1-ol > 2,2-difluropropan-1-ol> 2-chloro propan-1-ol> 3-chloro propan-1-ol> Propanol
