Question

write the respective chemical equations to show what happened 1) when ethanol is heated with concentrated H2 S o4 at 443 Kelvin 2) when ethanol react with ethanoic acid in presence of acid act as catalyst 3) sodium hydroxide is added to Ethonoic acid solid sodium hydrogen carbonate is added to ethonoic acid 4) ethanol react with sodium

Answer 1

1) ethanol -> with conc. sulphuric acid gives ethene + water
( sulphur above the arrow as it is a dehydrating agent )


2) esterification reaction

ethanol + ethanoic acid -------------> ethyl ethanoate + water

conc. H2SO4
C2H5OH + CH3COOH -----------------------> CH3COOC2H5 +H2O


3) ethanoic acid + sodium hydroxide ---------------------> sodium acetate +water

CH3COOH + NaOH ---------------------> CH3COONa + H2O

4) ethanol + sodium --------------------> sodium ethoxide + hydrogen gas

C2H5OH + Na -----------> C2H5ONa + H2
