methanol to ethanol conversion Step 1:  first we convert methanol to methyl cyanide where methanol is treated with PCL5 and we get methyl chloride then upon treated with kcn we get methyl cyanide step 2:   in step 2 methyl cyanide converted to acetic acid by hydrolysis in acid medium then acetic acid converted to ethanol by strong reducing agent lithium aluminium hydride 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
