Question

(1) Name the carboxylic acid used as preservative and write its molecular formula.
(2) Write the chemical equation representing the reaction of preparation of ethanol from ethane.
(3) Name the compound formed by heating ethanol at 443 K with excess of conc H2SO4​

Answer 1

Answer: 5 to 8 percent acetic acid

Explanation:ch3cooh

3) when ethanol is heated with h2so4 ethene is obtained
