Question

please solve the problem

Answer 1

Gas: H2

By dehydration reaction

C2H5OH -----> Ch2=Ch2

In the presence of conc. H2SO4

It acts as a dehydrating agent

Rate if it's helpful❤️

Answer 2

Ethanol can be converted to ethene in presence of concentrated sulphuric acid. It is called as dehydration reaction.

CH3-CH2-OH −→−−−−−−−−−−Concentrated H2SO4 CH2=CH2 + H2O

b) Ethene can be converted to ethane by addition of hydrogen molecule. It is known as hydrogenation reaction.

CH2=CH2 + H2 −→−−−−−−Nickel catalyst CH3-CH3
