conversion of ethylene to acetic acid

Image
step 1: in first step ethylene converted to ethyl bromide by using HBR which is an addition reaction  step 2: in second step ethyl bromide converted to ethyl alcohol by using aquous koh  as an reagent  step 3 :in 3rd step ethyl alcohol convert to acetic acid by using strong oxudising reagent   Related question; DCC Reagent(dicyclohexylcarbodiimide) 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+   a)Ethyl acetoacetate(CH3COCH2COOCH2CH3) reactions with 1)NaoEt 2)CH3CH2Br 3)NaOH/H2o 4)H3o+ b)2Ethyl acetate (2CH3COOEt) reaction with NaOEt/H3o+ c)Diethyl malonate (CH2 (COOEt)2 )reaction with 1)NaoEt 2) CH3CH2Br 3)H3O+ Toluene(Ph CH3) reaxts with1) NBS/hv,2)Pph3,Buli and 3)Acetone
