Concept Introduction:
Nylon-6 is a polymer which is made of a monomer 6-aminohexanoic acid. This follows a condensation step growth mechanism. So, it leaves small molecules as bye products while forming polymer. The condensation mechanism is an effective mechanism for the formation of polyamides.

Simo, Science, Vol. 315, p. 506, January 26, 2007) reported studies of dimethylsulfide (DMS), an important green-house gas that is released by marine phytoplankton. This gas represents the largest natural source of atmospheric sulfur and a major precursor of hygroscopic (i.e., cloud-forming) particles in clean air over the remote oceans, thereby acting to reduce the amount of solar radiation that crosses the atmosphere and is absorbed by the ocean. (a) Sketch the Lewis structure of dimethylsulfide, CH3SCH3, and list the bond angles in the molecule. (b) Use electronegativities to decide where the positive and negative charges lie in the molecule. Is the molecule polar?
