Document Summary

Nitrogen-containing molecules, especially triethylamine, are responsible for the smell of dead fish. Carbon-containing molecules are responsible for the smell of vanilla beans and cinnamon sticks. The study of compounds containing carbon combined with one or more of the elements hydrogen, nitrogen, oxygen, and sulphur, including their properties and their reactions. Organic: come from living things: e. g. sugar, obtained from sugarcane or the sugar beet. Inorganic: come from earth: e. g. salt, mined from the ground or extracted from the ocean. With four single bonds on carbon, tetrahedral. With a double bond and two single bonds, trigonal planar. With a triple bond and a single bond, linear. Carbon can bond to as many as four other atoms. Bonds to carbon are strong and nonreactive (covalent) Can form single, double, or triple bonds. Can bond together to form rings (6-carbon ring is stable) Compounds containing only carbon (c) and hydrogen (h)
