 CH3CH2OH + CrO3  =  CH3COOH
 (Ethanol)                    (Acetic acid)
 
CH3COOH + NaOH  =  CH3COONa
(Acetic acid)                (Sodium acetate)
 
CH3COONa + NaOH + CaO  =      CH4       +    Na2CO3 
(Sodium acetate)                     (Methane)
 
CH4  +   Cl2   =      CH3Cl
(Methane)        (Methyl Chloride)    
 
         CH3Cl           +   KOH(aq)  =   CH3OH
(Methyl Chloride)                          (Methanol)

CH3CH2OH+H2SO4 at 170-180 degree centigrade= CH2=CH2
CH2=CH2 Under ozonolysis +Zn/H20=2HCHO
HCH0+LiAlH4=CH3OH

H3C-CH2OH+HCL=H3C-CH2CL+H2O
H3C-CH2CL+KOH=H2C=CH2+KOH+H2O
H2C=CH2=HCOH(formaldehyde)
HCOH(formaldehyde)+H2=H3C-OH

Dear Student,
Please find below and attached image the solution of your problem.

Ethanol eventually oxidizes to ethanoic acid with the help ofK2​Cr2​O7​/H2​SO4.​
Decarboxylation ofethanoic acidgives methane, when chlorine is passed through methane forms methyl chloride.
In presence of aq. KOH methanol is produced.
Hence, all the reagents are required to convert ethanol to methanol.

Thanks and Regards
