  EMPRICAL FIRMULA:                                     The formula which shows the simplest whole number ratio of the elements present in one molecule of a compound is called empirical formula. For example,             Benzene = CH                                     Glucose = CH 2 O Ethane = CH 3                          Ethane = CH 2 Ethanoic acid = CH 2 O             Propene = Ch 2 Water – H 2 O ...
