Question

What happens when 'X' is heated with excess concentrated sulphuric acid at 443 K? Write chemical equation for the reaction stating the conditions for the reaction. Also state the role played by concentrated sulphuric acid in the reaction.

Name and draw the electron dot structure of hydrocarbon produced in the above reaction.

Write the name and structures of (i) aldehyde and (ii) ketone with molecular form C₃H₆O.

A saturated organic compound 'A' with two carbon atoms belongs to the homologous series of alcohols. On oxidation, it forms an organic acid 'B' with molecular mass 60 u. On heating 'A' with excess concentrated sulphuric acid at 443 K, an unsaturated hydrocarbon 'C' is formed. (i) Name A, B and C. (ii) Calculate molecular mass of C. (iii) What happens when a pinch of sodium carbonate is added to compound B ? Write chemical equation for the reaction. (iv) Draw electron dot structure of compound B.
