Two isomeric compounds, A and B. containing only carbon, hydrogen and oxygen are subjected to combustion analysis. One gram (1.0 g) of each compound on complete combustion gives 2.3 g of carbon dioxide and 0.93 g water. The relative molecular mass of each compound is 58.
i) Calculate the empirical and molecular formulae of A and B.
ii) Deduce the structural formulae of A and B
iii) State the type of isomerism exhibited by A and B
