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 products formed in the following reaction, C₆H₅-O-CH₃ + HI $\stackrel{\mathrm{Heat}}{\to }$ are-

1. C₆H₅OH and CH₃I 

2. C₆H₅I and CH₃OH

3. C₆H₅CH₃ and HOI

4. C₆H₆ and CH₃OI

Consider the following reaction,

Phenol$\stackrel{\mathrm{Zn}-\mathrm{dust}}{\to }$X$\underset{\mathrm{Anhy}.{\mathrm{AlCl}}_3}{\overset{{\mathrm{CH}}_3\mathrm{Cl}}{\to }}$Y$\stackrel{\mathrm{Alk}.{\mathrm{KMnO}}_4}{\to }$Z                                     

The product Z is

1. toluene

2. benzaldehyde

3. benzoic acid

4. benzene

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
