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.
What is a homologous series of carbon compounds ? Write the name and formula of three successive members of the homologous series of compounds having functional group – COOH.
Write the name of two carbon compounds in which carbon atoms are arranged in the form of a ring. Draw the structure of any one of the two.
The melting and boiling points of carbon compounds are generally low and they are largely non-conductors of electricity. State two conclusions based on these two properties.
