1.On dropping a small piece of sodium into an organic compound 'a' with molecular formula C2H6O in a test tube a brisk effervescence is produced. On bringing a burning splinter the gas evolved burns with a pop sound. Identify 'a' and write the chemical equation.
2. What will happen when you heat the organic compound 'a' at 443K with excess of conc. sulphuric acid?

1) The gas evolved burns with a pop sound, this indicates that the gas is hydrogen.
When ethanol reacts with sodium, sodium ethoxide is formed and hydrogen gas is released.
2C2H5OH + 2Na ------> 2C2H5ONa + H2
Hence, carbon compound 'X' is ethanol and gas 'Y' is hydrogen gas.
Ethanol on heating with conc. shuphuric acid gives ethene(CH2=CH2)
C2H5OH suphuric acid-------> CH2=CH2 + H2O
2.h2sO4 act as dehydrating agent
