Alcohols Phenol...

Assertion : Like bromination of benzene, bromination of phenol is also carried out in the presence of Lewis acid.

Reason : Lewis acid polarises the bromine molecule

Assertion : o-Nitrophenol is less soluble in water than the m- and p-isomers.

Reason : m- and p- Nitrophenols exist as associated molecules.

Assertion : Ethanol is a weaker acid than phenol.

Reason : Sodium ethoxide may be prepared by the reaction of ethanol with aqueous NaOH.

Assertion : Phenol forms 2, 4, 6 – tribromophenol on treatment with \(Br_2\) in carbon disulphide at 273K.

Reason : Bromine polarises in carbon disulphide.

Assertion : Phenols give o- and p-nitrophenol on nitration with conc. \(HNO_3\) and \(H_2SO_4\) mixture.

Reason : —OH group in phenol is o–, p– directing.

When phenol is treated with excess \(Br_2/\)water. It gives 

Ethanol and dimethyl ether form a pair of functional isomers. The boiling point of ethanol is higher than that of dimethyl ether. due to the presence of 

Which one of the following compounds is resistant to nucleophilic attack by hydroxyl ions?

When 3, 3-dimethylbutan-2-ol is heated with conc. \(H_2SO_4\) the major product obtained is:
