Document Summary
Ring structure , 4 rings base structure. Indigo dye plant dye: natural vs synthetic, vitamin c -- syntehized from lab and from natural is the same thing, natural doesn"t necessary, add acetyl groups, pain releaving. In tonic water: used to treat malaria. *** amide needs to ahve a carbonyl groups bside the nitrogen, needs to have an oxygen. When naming double bonds, find longerst chain with double bond, double bond has higher priority. One pi orbital left over, p orbital is perpieniduclar to trigonal planar. Extra p gets used, extra p orbital used to form seond bond 2 p orbital bond by side by side. Double bond side by side overlap o pie bond. Electrons could be located anywhere in p-orbital on two lobes. In the middle --- there is a sigma bond (diagram pie bond, gap between them. Alkene things get held in place no rotation. They have to be together so it prevents rotation.
