As the hydrocarbon part of an alcohol gets larger, the alcohol becomes less water soluble and more soluble in nonpolar solvents. Phenol is somewhat soluble in water. It acts as a weak acid in water, so a solution of phenol will be slightly acidic.
Why is alcohol more soluble in water than phenol?
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).
Which is more soluble in water phenol or alcohol?
Alcohols contain an OH group in which a hydrogen atom is attached to the electronegative oxygen atom, due to which it is capable of forming hydrogen bonds with the water molecule leading to greater solubility of alcohol in water. … Thus ethanol is more soluble in water compared to phenol.
Is phenol more soluble in water?
Phenols show acidic nature and hence are soluble in alkalies like NaOH, Na2CO3 etc. The acidic nature is due to formation of resonance stabilized phenoxide ion formed by losing a proton from -OH group. … Phenoxide ion is more polar than phenol itself. Hence is more soluble in water.
Is alcohol more soluble in water?
As alcohol is a polar solvent . It form Hydrogen Bond with water molecules while other hydrocarbons of comparable molecular masses does not form Hydrogen Bond due to being non – polar . Hence Alcohol is more soluble in water.
Which alcohol is more soluble in water?
Ethyl alcohol is more soluble in water than dimethyl class 12 chemistry CBSE.
Why alcohol is soluble in water?
Because alcohols form hydrogen bonds with water, they tend to be relatively soluble in water. The hydroxyl group is referred to as a hydrophilic (“water-loving”) group, because it forms hydrogen bonds with water and enhances the solubility of an alcohol in water.
Does phenol dissolve in NaOH?
Phenols are weak acids – in water, they ionize slightly to form phenoxide ion and hydronium ion, which makes the solution acidic. … If phenol is reacted with NaOH (a strong base), it is completely converted to the phenoxide ion, which is soluble in water because it is charged. Phenol itself is not very soluble in water.
Why Phenol is more polar than alcohol?
Phenol is more polar than ethanol. The O-H bond in phenol is more polar than the O-H bond in ethanol. In phenol, electron pair at O moves towards the conjugated benzene ring and shows resonance. Due to this resonance, the polarity of the O-H bond increases.
Is ethanol dissolve in water?
Ethanol is actually miscible in water, which means that the two liquids can be mixed in any proportion without any limit to their solubility.
Why is phenol soluble in hot water?
Phenol is somewhat soluble in water because of its ability to form hydrogen bonds with the water.
What makes phenol soluble in water?
Solubility of Phenols
The hydroxyl group in phenol is involved in the formation of intermolecular hydrogen bonding. Thus, hydrogen bonds are formed between water and phenol molecules which make phenol soluble in water.
Is an alcohol or aldehyde more soluble in water?
Contrary to aldehyde, alcohol has the -OH group and it can both act as a Hydrogen bond donor and accepter. This advantage makes alcohol more polar, thus making it more soluble in water.
Is an alcohol or ketone more soluble in water?
The alcohol group hydrogen bonds very easily with water. This means that molecules with more than one -OH group are often very soluble even though they may be large. This is the case with the sugars, such as glucose.
|alcohols, carboxylic acids, aldehydes, ketones, amides||Soluble|
Which alcohol has lowest solubility in water?
Of the given options, the largest alcohol of all is 1- pentanol and will thus have the least solubility in water. Thus, the correct answer is D. Note: Due to their polar nature, alcohols also have high boiling points.
