Does the formation of bonds mean a chemical reaction has occurred?

I was reading about how the components in a mixture haven't reacted with each other so can be separated via boiling which got me wondering what does it mean for them to react with each other. I've always thought of it as bonds forming but this doesn't seem true here as bonds exist between the atoms in the mixture so how do you classify whether they've reacted or not?

Bonds forming is an indication of a chemical reaction. A mixture does not create new bonds or break bonds. Sugar, for example, just mixes in with water. Each sugar molecule is surrounded by water molecules and becomes an aqueous solution. These are not “bonds” but rather intermolecular forces that hold the mixture together the way it is.
