C2H5OH can be differentiated from CH3OH by
reaction with HCl
reaction with NH3
by iodoform test
by solubility in water
C.
by iodoform test
Ethyl alcohol (C2H5OH) gives yellow crystal of iodoform with I2 and NaOH, but methyl alcohol (CH3OH) does not give iodoform with I2 and NaOH.
CH3CH2OH + 4I2 + 6NaOH → CHI3 + HCOONa + 5NaI + 5H2O
The reaction between an alcohol and an acid is called
esterification
saponification
hydrolysis
hydrogenation
