When sulphuric acid is treated with ethanol sulphuric acid behaves like________________?
Correct answer: B. a dehydrating agent
- A. an acid
- B. a dehydrating agent
- C. an oxidizing agent
- D. as sulphonating agent
Explanation
Concentrated sulphuric acid removes water from ethanol, promoting dehydration to ethene: C2H5OH → C2H4 + H2O. Thus, in this reaction, sulphuric acid acts mainly as a dehydrating agent rather than simply as an acid. The likely trap is acid, because H2SO4 donates protons, but its important role here is water removal.

About Reactions of Group IV Elements
Group IV, or Group 14, chemistry covers the trends from carbon and silicon to tin and lead, including their reactions with oxygen, halogens, water, acids and alkalis. It also examines the structures and properties of their oxides and chlorides, oxidation states, and the inert pair effect, rather than treating all members as equally metallic.
