An organic compounds having molecular formula C5H2O, which of the following is correct for
this compound:
O can be aldehyde and ketone
O can be alcohol and aldehyde
O can be alcohol and ether
O can be ether and ketone
These two different C2H6O compounds are called structural (or constitutional) isomers -
compounds with the same molecular formula but with different connections among their
constituent atoms. If you must break and make new bonds in order to convert one structure into
the other (not simply rotate the model around), then they are structural isomers. The concept of
isomers is very important in organic chemistry and biochemistry.
This is also another instance where condensed formulas can be very useful because they can
help you distinguish two isomers apart even when you don't have models.
Exercise 8) Can your models be interconverted by rotating bonds, or must the bonds be
broken first? What does that mean about these two structures?
