Question

What are structural isomers?

Answer 1

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

Explanation:

....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...
