I'm going off memory here so be sure to check this. I think the formula is the same, but the structure may be different. Just trying to point you in the right direction.

Both glucose and fructose have the same formula, however the position of the carbonyl group differs. -ie- it has a different structure. In glucose the carbonyl, an aldehyde, is at carbon 1, for fructose it is at carbon 2 and is a ketone. Glucose predominantly exists as a 6-membered ring and fructose predominantly exists as a five-membered ring.

Fructose is an isomer of glucose (isomers are molecules with the same chemical formula and often with the same kinds of bonds between atoms, but in which the atoms are arranged differently).

The "chemical" formula is the same - the "structural" formula is different. Change the position of one hydrogen atom in a tryptophan molecule and it becomes LSD-25. Structural formula is more specific than chemical formula because it gives the location of the atoms in a molecule whereas the chemical formula only tells you what atoms are in the molecule. And because structure of chemical determines its properties it is much more important to know.

Because the atoms are connected differently. Think of it this way. A water molecule is formed by an oxygen (O) atom, connected to two hydrogen (H) atoms. H2O, or H-O-H. Now suppose you had a hydrogen atom connected to a hydrogen and an oxygen. (This could never really happen, by the way. I'm just using it as an example because it's easy.) That could be written as H-H-O. It's still H2O, but the atoms are connected differently, so it's a different molecule.

Actually Paul's answer is the most accurate.
