 Organic Named Reaction

Chemical processes known as name reactions are those that are called after the researchers who first identified or created them. Scientist Lieben originated this fad in 1822. He developed the hypotheses that served as the foundation for the iodoform test by researching how various carbonyl compounds reacted with iodine and alkali. Due of this, the reaction was given the name LIeben Haloform Reaction, after Lieben. Hundreds of famous chemical reactions have been named for scientists as of late. All of these name reactions are crucial for board exams as well as for competitive exams like the IIT JEE and NEET.

Importance of Name Reactions

All name replies are crucial if you are in class 12 if you want to perform well on the board test and pass the JEE or NEET examinations. Here, we give you a list of significant named reactions in organic chemistry that you might refer to when doing your review. We have also included links to individual sites where specified reactions are mentioned along with thorough explanations, mechanisms, and applications.

• Wurtz Reaction

It is a coupling reaction in which two alkyl halides react with sodium to form a new alkane. For more details, visit Wurtz Reaction and Important Chemical Reactions for Class 12 Chemistry pages on Notes Booster.

• Swartz Reaction

It is a halogen exchange reaction in which alkyl halide is used as one of the reactants. For more details, visit Swartz Reaction and Important Chemical Reactions for Class 12 Chemistry pages on Notes Booster.

• Perkin Reaction

It is used to make cinnamic acids. It gives α,β-unsaturated aromatic acid by aldol condensation. For more details, visit the Perkin Reaction Mechanism page on Notes Booster.

• Sandmeyer Reaction

In the Sandmeyer reaction, a product of diazotization reaction, which is diazonium salt, is used to synthesize aryl halides.

• Gattermann Reaction

It is used in the synthesis of aromatic ring compounds such as aromatic halides and aromatic aldehydes.

• Balz-Schiemann Reaction

This reaction is used in the formation of fluorobenzene.

• Finkelstein Reaction

The reaction in which alkyl iodides are prepared by the reaction of alkyl chloride or alkyl bromide with sodium iodide in dry acetone is called Finkelstein Reaction.

• Fittig Reaction

When aryl halides react with metallic sodium in the presence of dry ether, it forms biphenyl as a major product. Then this reaction is known as the Fittig Reaction.

• Reimer – Tiemann Reaction

In the Reimer – Tiemann reaction, phenol reacts with chloroform in the presence of sodium hydroxide, as a result of which an aldehyde group gets attached to the ortho position of the ring.

• Kolbe’s Reaction

This reaction gives 2-hydroxybenzoic acid or salicylic acid by using phenol, sodium hydroxide and carbon dioxide.

• Stephen Reaction

In Stephen Reaction, nitrile reacts with SnCl₂ in the presence of HCl and gives imine hydrochloride, which on hydrolysis gives aldehyde.

• Gattermann – Koch Reaction

In the Gattermann – Koch reaction, benzene is treated with carbon monoxide in the acidic medium in the presence of anhydrous aluminium chloride to give benzaldehyde.

• Clemmensen Reduction Reaction

In the Clemmensen reduction reaction, the carbonyl group of aldehydes and ketones on reaction with zinc amalgam and conc. HCl is reduced to their corresponding hydrocarbon.

• Wolff Kishner Reduction Reaction

In Wolff Kishner Reduction Reaction, the carbonyl group of aldehydes and ketones reacts with hydrazine and forms hydrazone, which on heating with sodium hydroxide in boiling ethylene glycol reduces to CH₂ group.

• Aldol Condensation

In an aldol condensation reaction, two molecules of an aldehyde or ketones get condensed and form β - hydroxy aldehyde or β - hydroxy ketone, respectively, in the presence of dilute alkali.

• Carbylamine Reaction

When aliphatic or aromatic primary amines are heated with chloroform, and ethanolic potassium hydroxide produces carbyl amines or isocyanides. This reaction is known as the carbylamine reaction
