Question

Heating n butyl alcohol with conc sulphuric acid

Answer 1

Answer:

Concentrated sulphuric acid acts as a dehydrating agent in this reaction and removes a molecule of water.

Note: When Ethanol (x) reacts with sodium colorless Hydrogen gas (z) is evolved.

CH3CH2OH + Na--- C2H5ONa + H2

a) Ethanol

b) Ethene

c) H2

Answer 2

In this Question, It is given that A compound 'X' on heating with excess concentrated h2so4 acid at 443k gives an unsaturated compound y. X also reacts with na metal to evolve a colorless gas z .

Required Compound X is (Ethanol) or C2H50H

Required Unsaturated Compound Y is Ethene or C2H4

Required Colourless Gas Z is H2 ( Hydrogen gas)
