4-chloro-3, 5-dimethyl phenol is called

• Chloramphenicol

• Paracetamol

• Barbital

• Dettol

The function of AlCl₃ in Friedel-Craft's reaction is

• to absorb HCl

• to absorb water

• to produce nucleophile

• to produce electrophile

Phenol $\stackrel{{\mathrm{NaNO}}_2/ {\mathrm{H}}_2{\mathrm{SO}}_4}{\to } \mathrm{B} \stackrel{{\mathrm{H}}_2\mathrm{O}}{\to } \mathrm{C} \stackrel{\mathrm{NaOH}}{\to } \mathrm{D}$

Name of the above reaction is

• Liebermann's reaction

• Phthalein fusion test

• Reimer-iemann reaction

• Schotten-Baumann reaction

The silver salt of a fatty acid on refluxing with an alkyl  alide gives an

• acid

• ester

• ether

• amine

A compound A has a molecular formula C₂Cl₃OH. It reduces Fehling's solution and on oxidation, gives a monocarboxylic acid B. A can be obtained by the action of chlorine on ethyl alcohol. A is :

• chloroform

• chloral

• methyl chloride

• monochloroacetic acid

The reaction in which phenol differs from alcohol is:

• it undergoes esterification with carboxylic acid

• it reacts with ammonia

• it forms yellow crystals of iodoform

• it liberates H₂ with Na metal

An organic compound A containing C, H and O has a pleasant odour with boiling point of 78°C. On boiling A with concentrated H₂SO₄, a colourless gas is produced which decolourises bromine water and alkaline KMnO₄. The organic liquid A is:

• C₂H₅Cl

• C₂H₅COOCH₃

• C₂H₅OH

• C₂H₆

Methyl bromide is converted into ethane by heating it in ether medium with :

• Al

• Zn

• Na

• Cu

The catalyst used in the preparation of an alkyl chloride by the action of dry HCl on an alcohol is:

• anhydrous AlCl₃

• FeCl₃

• anyhydrous ZnCl₂

• Cu

Which of the following compound would not evolve CO₂ when treated with NaHCO₃ solution?

• Salicylic acid

• Phenol

• Benzoic acid

• 4-nitrobenzoic acid
