The solubility of phenol in water is lower. This can be attributed to:

1. Non-polar nature of phenol

2. Acidic nature of -OH group

3. Non-polar hydrocarbon part in phenol

4. None of the above

Phenol and benzoic acid can be distinguished by:

1. Aqueous NaHCO₃                           

2. Aqueous NaNO₃

3. Aqueous NaOH                               

4. Conc. H₂SO₄

The compound having lowest boiling point among the following is -

1. Phenol                                 

2. o-Nitrophenol

3. m-Nitrophenol                       

4. p-Nitrophenol

The ionisation constant of phenol is higher than that of ethanol because -                   

1. Phenoxide ion is bulkier than ethoxide

2. Phenoxide ion is a stronger base than ethoxide

3. Phenoxide ion is stabilised through delocalisation

4. Phenoxide ion is less stable than ethoxide

Which represents Riemer-Tiemann reaction?

The boiling point of p-nitrophenol is higher than that of o-nitrophenol because -               

1. NO₂ group at p-position behaves in a different way from that at o-position.

2. Intramolecular hydrogen bonding exists in p-nitrophenol.

3. There is intermolecular hydrogen bonding in p-nitrophenol.

4. p-Nitrophenol has a higher molecular weight than o-nitrophenol.
