							Dear Student

1) Ethanol (C2H5OH) is dehydrated in the presence of excess conc. sulphuric acid to produce ethene (C2H4). It is called Dehydration reaction.
CH​3-CH2-OH →CH2=CH2+ H2O

2)Ethene upon hydrogenation in the presence of a catalyst like nickel or palladium yields ethane.It is known as hydrogenation reaction.
CH2=CH2+ H2 → CH3-CH3

I hope this answer will help you.
Thanks & Regards
