When phenol is reacted with chloroform and an alkali like NaOH, the compound formed is salicylaldehyde. If we use pyrene in place of chloroform, the product obtained is:

1. Salicylaldehyde

2. Phenolphthalein

3. Salicylic acid

4. Cyclohexanol

When phenol is treated with excess bromine water, it gives:

(1) m-bromophenol

(2) o- and p-bromophenol

(3) 2,4-dibromophenol

(4) 2,4,6-tribromophenol

In the reaction, Phenol $\underset{\mathrm{DIstillation}}{\overset{\mathrm{Zn}}{\to }}$(A) $\underset{\mathrm{Conc}. {\mathrm{HNO}}_3 \mathrm{at} 60°\mathrm{C}}{\overset{\mathrm{Conc}. {\mathrm{H}}_2{\mathrm{SO}}_4}{\to }}$(B) $\underset{\mathrm{NaOH}\left(\mathrm{aq}\right)}{\overset{\mathrm{Zn}}{\to }}$(C)

The compounds (A),(B) and (C) are of the following:

(1) benzene, nitrobenzene and aniline

(2) benzene, dinitrobenzene and m-nitroaniline

(3) toluene, m-nitrobenzene and m-toluidine

(4) benzene, nitrobenzene and hydrazobenzene

Phenol on oxidation gives chloranil. The oxidant used is:

1. K₂S₂O₈

2. KMnO₄

3. KCIO₃ + HCl

4. none of these

A characteristic group test for phenolic gp. is:

1. Liebermann's nitroso reaction

2. coupling with diazonium salt

3. aqueous FeCl3

4. all of the above

Phenol can be converted into salicylic acid by

1. Etard's reaction

2. Kolbe's reaction

3. Phenol with CCl₄ in basic medium
