Getting Started Some Terminology

In this section, we introduce and define some very basic terms. Most are discussed in greater detail in later sections, and your understanding of these terms should grow as you proceed through the chapter. 

Neither energy nor matter is transferred between the system and its smrormdings. 

When mass, speed, acceleration, and distance are expressed in SI units, the units of both kinetic energy and work will be kg m s, which is the SI unit of energy—the joule 0). That is, 1J = 1 kg m s .

Consider the following situations a stick of dynamite exploding deep within a mountain cavern, the titration of an acid with base in a laboratory, and a cylinder of a steam engine with all of its valves closed. To what type of thermodynamic systems do these situations correspond

But before we can get started, we need to know some basics about C=0 bonds. Let s start with a bit of terminology that we will use throughout the entire chapter. Instead of constantly using the expression C=0 double bond, we will call it a carbonyl group. This term is NOT used for nomenclature. You will never see the term carbonyl appearing in the lUPAC name of a compound. Rather, it is just a term that we use when we are talking about mechanisms, so that we can quickly refer to the C=0 bond without having to say C=0 double bond all of the time. 

It is an almost impossible task to write a useful definition of supramolecular chemistry. The field is ever changing as it advances, and researchers will have their own understanding and sets of terminology. Rather than trying to limit the field or "claim" certain areas, what follows will attempt to be a simple introduction for the newcomer into the sorts of areas in which the concepts of supramolecular chemistry, broadly defined, may be of some use. In short, here are some things to think about to get you started.
