Describe the plum-pudding model of the atom.
Solution : Compo unds with similar molecular formula but different arrangement of atoms and having different properties are called as isomers. the compounds given are : The given compounds are 2-Chlorobutane and 1-Chlorobutane. The compound in which chlorine i s ttached to irst carbon is named as 1-Chlorobutane, and the other compound which, chlorine i s attached to econd carbon is named as 2-Chlorobutane. Both the compounds are made up of 4 atoms of carbon, 9 atoms of hydrogen and 1 atom of chlorine. Hence, Molecular formula for both the compounds is C H Cl. Althoug4b9h the compounds have same molecular formula C H Cl, the 4a9ment of halogen in the compound differs. Chlorine is the halogen in the given compounds. In one compound chlorine is attached to f irst carbon and in another it is attached to s econd carbon. Therefore, as per the definition of isomers, both compounds have same molecular formula and their structuralarrangement is different, hence they are isomers.
