How does ethanol reacts with
(a) Metallic sodium
(b) Acetic acid
(c) Conc.H2S04
उत्तर
Ethanol reacts as follows
(a) Metallic sodium:
\[\ce{2C2H5OH + 2Na -> 2C2H5ONa + H2}\]
(b) Acetic acid:
\[\ce{C2H5OH + CH3COOH <=>[concH2SO4] CH3COOC2H5 + H2O}\]
(c) Conc. H2SO4
\[\ce{C2H5OH ->[conc.H2SO4][170°C] CH2 = CH2 + H2O}\]
