What is a discreet molecule?
One of my exam questions in chem was, "Which of the following does not exist as discreet molecules: HCl, LiCl, or BrCl?" I picked LiCl and I was right, but it was just luck. What is a discreet molecule?

A discreet molecule is a single molecule. Since both BrCl and HCl exist a gases then they can exist as discreet molecules.
But LiCl is a salt and can only exist in a salt matrix which consists of MANY more LiCl units.
It cannot exist as a gas, but can be dissolved, but when dissolved it is no longer LiCl it is Li+ and Cl- ions, not longer a molecule at all.
