Convert ethanol into ethene using (a) solid dehydrating agent (b) hot conc. H2SO4 ? Give only balanced equations.
Ethanol can be converted into ethene which can be changed into ethane. Choose the correct word or phrase from the brackets to complete the following sentences.
(a) The conversion of ethanol into ethene is an example of (dehydration, dehydrogenation). (b) Converting ethanol into ethene requires the use of (conc. HCl, conc. HNO3,conc.H2SO4). (c) The conversion of ethene into ethane is an example of (hydration, hydrogenation). (d) The catalyst used in the conversion of ethene into ethane is commonly (iron, nickel, cobalt).
(i) How will you distinguish between dilute H2SO4 and conc H2SO4? (ii) How will you distinguish between conc. HCl and conc. H2SO4? (iii) Give main differences between drying agent and dehydrating agent.
Explain clearly how conc. H2SO4 is used as dehydrating as well as drying agent.
