Robinson annelation reaction

Image
Robinson annelation reaction conjugated adition reaction or Michael addition reaction followed by intermolecular aldol and dehydration process is called Robinson annelation reaction in Robinson annelation reaction since the cyclisation  involve hence always thermodynamically controlled enolate ion formed initially and major product is dehydration product. since the Robinson annelation reaction is always thermodynamically controlled so we cannot obtain kinetically controlled less substituted product related question; oxidation of alcohol ,Types of alcohol,strong oxidizing agentsweak oxidizing agents Toluene 1)Oxidation with kmno4 mechanism 2)Benzoic acid (C6H5cooH)+Socl2 3)Benzoyl chloride (C6H5Cocl) +LiAlH[ (OC (CH3)3]/H+ 4)Benzaldehyde (C6H5CHo)+CH2OHCH2OH/H+ Activity coefficient calculation example ,Debye-Huckel equation,ionic strength determination

oxidation of alcohol ,Types of alcohol,strong oxidizing agentsweak oxidizing agents

Introduction the functional group of alcohol is -OH. the first member of alcohol family is methanol. alcohols are polar in nature they are they are generally in liquid form due to strong intermolecular hydrogen bonding. Types of alcohol alcohols are divided into 3 categories  a)1 degree alcohol or primary alcohol  b)2 degree alcohol or secondary alcohol c)3 degree alcohol or tertiary alcohol. primary alcohols are -ch2oh  secondary alcohols are -choh  tertiary alcohols are -coh depending upon the oxidizing agents different alcohols are oxidised to different compound strong oxidizing agents are KMnO4 ,K2 cr2o7/ concentrated H2SO4 , na2cr2o7/ concentrated H2SO4. when primary alcohols are oxidized by strong oxidizing agents than acid formed  for example methanols become methanoic acid or formic acid  ethanol oxidized to ethanoic acid or acetic acid  propanol oxidised to  propanoic acid  butanol oxidized to butanoic acid  pentanol oxidised t...

methane to ethane and ethane to methane conversion ,halogenation reaction, wurtz reaction, grignard reaction, decarboxylation reaction

Image
Introduction: methane and Ethane both are hydrocarbon and they are belongs to alkene family the formula of methae is ch4 and the formula of Ethane is c2h6. how to convert methane to ethane there are two process by which we can convert methane to ethane   process 1  firstly we can we convert  methane to methyl chloride by treating methane with chlorine in presence of sunlight (halogenation reaction) after that methyl chloride convert to Ethane via wurtz reaction in which methyl chloride treated with sodium in presence of dry  ether solvent . process 2  In grignard reaction firstly we convert methyl chloride to methyl magnesium chloride by reacting methyl chloride with magnesium in dry ether solvent in the second step of grignard reaction methyl magnesium chloride react with methyl chloride and it produced  Ethane . Methane to ethane Ethan to methane conversion the carbon number in ethane is 2 and the carbon number in methane is 1 so we need to decrease the...
