  Chemical Reactions  

In chemistry there are many types of chemical reactions some reactions are in generally known as naming reactions. Some reactions are: - Wurtz reactions, Grignard reactions, Fitting reactions, Wurtz Fitting reactions, Williamson's synthesis, Kolbe's Electrolysis reactions, Friedel Craft Acylation reactions, Friedel Craft Alkylation reactions, Diazotization Reactions, Hoffmann's Bromide reactions, Carbylamine reactions, Riemer - Tiemann Reaction,  Finkelstein reaction, Clemmensen reduction, Esterification Reaction, Cannizzaro's Reactions, Elb's Reactions, Ullmann reactions, Étard's reactions, Sandmeyer reactions, Aldol Condensation reaction, Markownikoff's Rule, Antimarkownikoff's rule, Tollen's Reagent, Fehling solution, 

✅Wurtz Reactions- The reactions in which higher alkanes are prepared by heating of alkyl halides (RX) with sodium (Na) in the presence of dry ether is called Wurtz reactions.

✅Grignard Reactions: - The reactions in which alkyl maghalide(RMgX) is prepared by heating or alkyl halide (R-X) with Mg in the presence of dry ether is called Grignard Reactions.

✅Fitting Reactions: -The reactions in which di aryl is prepared by heating of two molecules of aryl halides with sodium in the presence or dry ether is called fitting reactions.

✅Wurtz Fitting Reactions: - The reactions in which allyl benzene is prepared by heating of alkyl halide and aryl halides with Na in the presence of dry ether is called Wurtz fitting reactions.

✅Williamson's Synthesis: -The reactions in which ethers (-0-) are prepared by heating of alkyl halides with sodium alkoxide (Na-0-R) or, sodium phenoxide is called Williamson's synthesis.

✅Kolbe's Electrolysis Reactions: - The electrolysis of Na/K salts of carboxylic acid in aqueous solution to give alkane, alkene and alkyne is called Kolbe' s electrolysis reactions.

✅Friedel Craft Alkylation: - he reactions in which alkyl benzene is prepared by heating of alkyl halides with benzene in the presence of anhydrous AlCl3 is called Friedel craft alkylation.

 

✅Friedel craft Acylation:  - The reactions in which aromatic ketones (R-CO-Ar) are prepared by heating of acid chloride(R-CoCl) or, anhydride with benzene in the presence of anhydrous AlCl3 is called Friedel Craft Acylation.

✅Diazotization Reactions: - The reactions in which benzene diazonium chloride is prepared by heating of aniline, dilute HCl/ H2So4 and cold HNO2 at 0'c-5'c is called diazotization reactions.

✅Hoffmann's Bromide reactions: - The reactions in which P- amine is prepared by heating of amides (R-CoNH2), Br2 and KOH/NaOH solution is called Hoffmann's bromide reactions

✅Carbylamine Reactions: -The reactions in which alkyl isocyanide is prepared by heating of P- amine (R-NH2), chloroform and KOH solution is called carbylamine reactions.

✅Riemer- Tiemann Reactions: - The reactions in which hydroxy benzaldehyde ( salicyldehyde) is prepared by heating of phenol: CHCI3 and KOH solution at 340k is called Riemer Tiemann reaction.

✅Finkelstein Reactions: - The reactions in which chloroalkane or bromoalkene is treated with Nal dissolved in acetone is called Finkelstein reactions. 

✅Clemmensen Reduction: -The reactions in which aldehyde or ketone is reduced wit ZnHa/conc. HCI to form alkanes is called Clemmensen reduction.

✅ Esterification Reactions: - The reactions in which esters is prepared by heating of carboxylic acid with an alcohol in the presence of conc. H2s04 is called esterification reactions.

✅Cannizzaro's Reactions: - The reactions in which the aldehyde is treated with conc. NaOH to form sodium salt and an alcohol is called Cannizzaro's reactions. 

✅Elb's Reactions: - The reaction in which phenol is oxidised with K2S2O8 to form O/P dihydroxy benzene is called Elb's reactions.

✅Ullmann Reactions: - The reactions in which two molecules of iodo benzene is heated with Cu to form biphenyl is called Ullmann reactions. 

✅Étard's Reactions: - The reactions in which Toluene (methyl benzene) is oxidised with chromyl chloride in the presence of CCI4 or CS2 to form benzaldehyde is called Étard's reactions.

✅Sandmeyer Reactions: - The conversion of benzene diazonium chloride into chlorobenzene, bromobenzene or cyanobenzene with CuCl/HCI, CuBr/HBr, CuCn/KCn is called Sandmeyer reactions.

✅Aldol Condensation Reactions: - The reactions in which aldehyde or ketones is heated with dil. NaOH to form B-hydroxy aldehyde or B- hydroxy Ketones is called aldol condensation reactions.

✅ Markownikoffs Rule: - According to this rule, the negative part or a reagent (HX) will be attached to an alkene or alkyne with less numbers or hydrogen atoms is called Markownioff's rule.

✅Antimarkownikoff's rule: - According to this rule, the negative part of a reagent (HX) will be attached to an alkene or alkyne with higher number or hydrogen atom in the presence of peroxide is called Antimarkownikoff's rule. 

✅Tollen's Reagent: - The mixture of NH40H and AgNo3 is called tollens reagent.

✅Fehling Solution: - The mixture of Cuso4 and NaOH is called Fehling solutions.
