These are compounds with the SAME formula.....


....but whose connectivity differ...

Organic chemistry provides a WEALTH of examples of structural isomers. A formula of #C_4H_10# allows TWO structural isomers (which are?). And a A formula of #C_5H_12# generates THREE structural isomers (which are?).

As the formula gets larger, the opportunity for isomerism is magnified.


Can you draw the structure of the three isomers of pentane? I think you could (and should) do this...
