    29 (a)
    A carbon compound ‘P’ of molecular formula C2H6O\mathrm{C_2H_6O} is found to be neutral when tested with red and blue litmus. A gas that burns with a pop sound is produced when sodium metal reacts with compound ‘P’. (i) Identify the compound ‘P’. (ii) The carbon compound ‘P’ is heated with conc. H2SO4\mathrm{H_2SO_4} at 443 K to produce compound ‘Q’. (I) Write the chemical equation for the reaction. (II) What is the role of conc. H2SO4\mathrm{H_2SO_4} in this reaction ? (iii) What is likely to be observed on heating compound ‘P’ with ethanoic acid with an acid as a catalyst ? Write the chemical equation for the reaction.
