Does cyclohexanol dissolve in water?
Cyclohexanols are compounds containing an alcohol group attached to a cyclohexane ring. Cyclohexanol is soluble (in water) and an extremely weak acidic compound (based on its pKa).
Why cyclohexanol is slightly soluble in water?
It is more compact than the group (-C6H13) in hexan-1-ol which is a straight chain alcohol. Due to smaller size, the cyclohexyl group is more exposed to hydrogen bonding with H2O molecules in water as compared to the other alkyl group. therefore, cyclohexanol is more soluble in water than hexan-1-ol.

What are the products of dehydration of cyclohexanol?
The dehydration of cyclohexanol is carried out in such a way that the product, cyclohexene, distils from the reaction mixture as it is formed, the distillation technique serves to remove the olefin from contact with the sulphuric acid before polymerization can set in and it also serves as a first stage in the eventual purification of the olefin.
What is the pKa of functional groups?
For basic functional groups, the pKa refers to the acid strength of the base’s conjugate acid. Each functional group of a molecule with multiple ionizable functional groups has its own distinct pKa. The pKa of a specific functional group is fixed and cannot be changed.
What is the pKa of acetylsalicylic acid?
Physical properties. Aspirin, an acetyl derivative of salicylic acid, is a white, crystalline, weakly acidic substance, with a melting point of 136 °C (277 °F), and a boiling point of 140 °C (284 °F). Its acid dissociation constant ( pKa) is 3.5 at 25 °C (77 °F).
What is the pKa of chloroacetic acid?
PKa value depends upon the strength of acid. If acid is strong than PKa value would be less and vice versa. So PKa-acetic acid is 4.23 and chloroacetic acid is 2.3.
