ISOMERISM AND STERIOCHEMISTRY
“ Different compound having same molecular formula are called isomers and phenomenon are called isomerism”. Greek=isos—to same or equal, merisis—part or constituents. Isomerism is classified in to two parts----- 1=structural isomerism 2=stereo isomerism structural isomerism— Same molecular formula but different structural formula. Ex=n-butane & iso - butane structural isomerism are 7 types— 1=chain ,nuclear & skeleton isomerism— same molecular formula but different carbon chain. Ex-- n-pentane , iso pentane & neo pentane, Butanol-1 2-methyl propenol-1, ...
