Why is phenol more soluble in water than cyclohexanol?
Phenol is more soluble in water than Cyclohexanol due to high polarity of O-H bond in phenol.
Why is cyclohexanol not soluble in water?
The molecule has a large non-polar part which forms strong London dispersion forces with other cyclohexanol molecules. The formation of hydrogen bonds with water does not compensate for the loss of these London forces. Cyclohexanol bonds to itself better than to water.
Why is phenol more soluble in water?
Phenol is somewhat soluble in water because of its ability to form hydrogen bonds with the water.
Why is phenol more soluble in water than alcohol?
Phenols : Phenols also form hydrogen bonds with water and hence are soluble in water. However, the solubility of phenols is much lower than that of alcohols due to the presence of the larger hydrocarbon part (benzene ring).
Is phenol or cyclohexanol more soluble?
The solubility of phenol is 83 g/L, while that of cyclohexanol is 36 g/L.
Why is phenol A stronger acid than cyclohexanol?
Phenol is more acidic than cyclohexanol and acyclic alcohols because the phenoxide ion is more stable than the alkoxide ion. In an alkoxide ion, such as the one derived from cyclohexanol, the negative charge is localized at the oxygen atom.
Is cyclohexanol more soluble water?
The OH group of cyclohexanol is more exposed and is more available for hydrogen bonding with water. Hence, cyclohexanol is more soluble in water than the hexanol-1.
Is cyclohexanol more soluble in water or in ether?
Cyclohexanol

Why is phenol less soluble in water?
It is due to its ability to form hydrogen bonding with water molecules. However the large part of phenol molecule is phenyl group that is non polar and hence its solubility if limited in water. However the polarity of this part too increases in phenoxide ion. But phenol is not soluble in aqueous solution of NaHCO3.
Which is more soluble in water phenol?
Water is a polar solvent. Hence polar substances like salts are more soluble in it. Phenoxide ion is more polar than phenol itself. Hence is more soluble in water.
Why phenol is less soluble in water than alcohol?
Phenols and alcohol both form hydrogen bonds with water and hence are soluble in water. However, the solubility of phenols is much lower than that of alcohols due to the presence of the larger hydrocarbon part (benzene ring).
How can phenol be distinguished from cyclohexanol solubility?
We can distinguish cyclohexanol from phenol by reacting them separately with a ferric chloride solution; it gives a violet color when ferric chloride reacts with phenol, while it remains colorless when reacted with cyclohexanol.
What is the solubility of phenol and cyclohexanol?
The solubility of phenol is 83 g/L, while that of cyclohexanol is 36 g/L. Both of them have a hydroxy group, and can form hydrogen bonds with water.
Which layer of phenol is soluble in water?
The top layer is a solution of phenol in water, and the bottom one a solution of water in phenol. Phenol is somewhat soluble in water because of its ability to form hydrogen bonds with the water.
What are the properties of phenol?
Properties Phenol is a organic compound appreciably soluble in water, with about 84.2 g dissolving in 1000 mL (0.895 M ). Homogeneous mixtures of phenol and water at phenol to water mass ratios of ~2.6 and higher are possible.
Why is cyclohexanol more acidic than alcohol?
Cyclohexanol is an alcohol. It is teached in highschool that phenols are more acidic than alcohols. Because phenol has highly activating group OH and hence even after losing a Hydrogen the atom stabilises by resonance from OH ‘s lone pair
