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