Does this refer to a rxn in which water is lost or can it be any other small molecule as well?

Thanks

A hydrolysis reaction is a reaction in which water is a reactant (typically, water reacts with an organic molecule to split the molecule in two).

A condensation reaction (aka dehydration synthesis) may be the reaction to which you are referring.  In this type of reaction, two organic molecules are joined together and they produce water as a byproduct.  Some reactions which produce other small molecule byproducts (e.g. alcohols) as leaving groups are also referred to as condensation reactions.  A good example is a claisen condensation (http://en.wikipedia.org/wiki/Claisen_condensation).

Thanks...I was quite confused because I was hearing about hydrolysis in what I thought were multiple contexts.
