i) CUMENE PROCESS- Phenol is manufactured from the hydrocarbon, cumene (isopropylbenzene). In first step
molecular oxygen reacts with cumene to form cumene hydroperoxide (via free radical mechanism), then treating this
peroxide compound with dilute acid reasult in the formation of phenol as well as acetone. This reaction involves a phenyl
migration mechanism.
ii) CARBYLAMINE TEST- Aliphatic and aromatic primary amines on heating with chloroform and ethanolic potassium
hydroxide form isocyanides or carbylamines which are foul smelling substances. Secondary and tertiary amines do not
show this reaction.
iii) COUPLING REACTION or DIAZO COUPLING Reaction- Benzene diazonium chloride reacts with phenol or aniline
to form azo dyes.
NAME REACTIONS
1. Sandmeyer’s reaction- Benzene diazonium salt with cuprous chloride or cuprous bromide results in the
replacement of the diazonium group by –Cl or –Br.
2. Wurtz reaction- Alkyl halides react with sodium in dry ether to give hydrocarbons containing double the number
of carbon atoms present in the halide.

3. Wurtz-Fittig reaction- A mixture of an alkyl halide and aryl halide gives an alkylarene when treated with sodium in

6. Swarts reaction- H3C-Br +AgF → H3C-F + AgBr
7. Kolbe’s reaction- When phenol reacts with sodium hydroxide, phenoxide ion generated undergoes electrophilic
substitution with carbon dioxide and forms salicylic acid.

give aldehyde.
11. Clemmensen reduction- Aldehydes and ketones are reduced to alkanes on treatment with zinc- amalgam and
concentrated hydrochloric acid. (Zn-Hg/conc. HCl) CH3 –CHO  CH3–CH3
12. Wolff-Kishner reduction- Aldehydes and ketones are reduced to alkanes on reaction with hydrazine followed by
heating with potassium hydroxide(NH2-NH2/KOH) in ethylene glycol. CH3 –CO - CH3  CH3 –CH2 - CH3

14. Aldol condensation- Aldehydes and ketones having at least one α-hydrogen undergo a reaction in the presence of
dilute alkali form β-hydroxy aldehydes (aldol) or β-hydroxy ketones (ketol), respectively.
15. Hell-Volhard-Zelinsky reaction- Carboxylic acids having an α-hydrogen are halogenated at the α-position on
treatment with chlorine or bromine in the presence of small amount of red phosphorus to give α-halocarboxylic acids.
16. Hoffmann bromamide degradation reaction
Primary amines can be prepared by treating an amide with bromine in an aqueous or ethanolic solution of sodium
hydroxide.The amine so formed contains one carbon less than that present in the amide.
17. Cannizzaro reaction: This is a disproportionation reaction in which aldehyde undergoes self-oxidation and reduction.

18. Etard’s reaction: (For aromatic aldehyde) Toluene reacts with chromyl chloride (CrO2Cl2) in CS2 or CCl4 to form
benzaldehyde.
19. Gatterman- Koch reaction:(for aromatic aldehyde) When a mixture of CO and HCl gas is passed through benzene
in presence of anhydrous AlCl3 + CuCl, benzaldehyde is formed.
20. Gattermann and sandmayer

halobenzene is called sandmeyer’s reaction. Ar-N2Cl + CuCl + HCl Ar-Cl + N2

salt.
27. DIAZOTIZATION REACTION
The conversion of primary aromatic amines into diazonium salt is known as diazotization reaction.The diazotization reaction
is characterize in the joining two N-atoms (diazo).
