m.
Answer the following question:
1.
Dehydration of Ethanol
i.
Write the chemical equation for the dehydration of ethanol.
\(2CH_3 COOH+Na_2 CO3 \to 2CH_3 COONa+CO_2 +H_2 O\)
\(CH_3 CH_2 OH\to CH_3 CHO + H_2\)
\(CH_3 CH_2 OH\to CH_2 =CH_ 2+H_2 O\)
\(CH_3 CH_2 OH + CH_3 COOH\to CH_3 COOC_2 H_5 + H_2O\)
ii.
Name the catalyst used in this reaction.
potassium permanganate
Concentrated sulphuric acid
Nickel
Platinum
iii.
Name the products formed.
Ethanoic acid and water
Ethene and hydrogen gas
Ethene and water
Ethanal and hydrogen gas
iv.
Name the type of reaction.
