Question

On dropping a small piece of sodium in a test tube containing carbon compound X with the molecular formula C2H6O,a brisk effervescence is observed and a gas Y is produced.On bringing a burning splinter at the mouth of the test tube for the gas evolved burns with pop sound. Identify X and Y. Also write the chemical equation for the reaction. Write the name and structure of the product formed, when you heat X with excess conc. sulphuric acid.

Answer 1

x - ethanol
y - CO2
2C2H5OH+Na2----------> C2H5ONa+ H2
C2H5OH----------------H2SO4------->C2H4(ETHENE)+H2O

Answer 2

Here the 'X' is ethanol.

And

'Y' is carbon dioxide..(CO2)

Reaction : C2H5OH +Na2 —› C2H5 ONa +H2

Ethane + H2O.......is formed.
