Question

convert methanol to ehanol for class 12

Answer 1

First form Ch3Cl by action of KCl and then use dilute HCl forming Ch3COOH then reduce it to Ch3ch2oh by using LiAlH4.

Answer 2

firstly methanol convert to methyl alcohol in presence of PI3 and then to methyl magnesium iodide in presence of mg/ether and then apply grignard reaction

 CH3-OH + HBr ------> CH3Br + H2O 

2CH3Br -------->CH2=CH2(Alc.Koh)

treat ethene with h2so4 to give enthanol..

CH3OH (methanol) + red P/I2 or, HI ---->CH3I (methyl iodide) + KCN ----->CH3CN(methyl cyanide) +Na/C2H5OH ------>CH3CH2NH2 +HNO2 ------->CH3CH2OH (ethanol)

CH3OH+HCl----->CH3Cl 2CH3Cl+2Na------->CH3-CH3+2NaCl(DryEther)CH3-CH3+HCl----->CH3-CH2-Cl+H2CH3-CH2-Cl+KOH(aq)----->CH3-CH2-OH

CH3-OH +[O]------>HCHO +H2O (Cu 400°C 200atm).HCHO+CH3-Mg-Br------>CH3-CH2-OH +Br-Mg-OH Treat in the presence of dry ether

FIRST REACT CH3OH with PCl3 to get Methyl chloride. Then react it with Mg/ether to form methly magnecium chloride further react the product with formaldehyde to get C2H5OH.
