I don't mean at the receptor end but dispersion? Why some are more pungent than others. How far does it travel? Why can an odor cling to fabric, and other things.

Dispersion: Odors behave like other gases do. Some rise, some sink, and some just scatter randomly.
Why are some more pungent? Different chemistry. Some molecules are interpreted as being foul, and some are pleasant.
How far does it travel? All over the world, potentially. However, most are so dispersed into the air by then that you can't smell anything.
Why can an odor cling to fabric? If a piece of fabric has accumulated a collection of odor-causing molecules, and it releases them slowly, odors can appear to cling to fabric. Bacteria on the fabric can also create gaseous odors.

molecules break bonds that keep them together with the other molecules of that substance and they rise on thermals or convection currents of gas.
