Removing Functional Groups from a Molecule: Methods and Possibilities

[Stratosphere]

Is there a way to "remove" functional groups? I see a lot of pages online that show how you can change them, but not how to completely remove one from a molecule.

Is it even possible?

It depends on the functional group how it's done. Generally it is possible to completely replace them with hydrogens if that is what you are asking. What's the fun in that, though? Alkanes are boring.
