Classes of Halides Alkyl: Halogen, X, is directly bonded to sp3 carbon. Vinyl: X is bonded to sp2 carbon of alkene. Aryl: is bonded to sp2 carbon on benzene ring. Examples:

Reactivity of C=C C—C Electrons in pi bond are loosely held Electrophiles are attracted to the pi electrons. · Carbocation intermediate forms. Nucleophile adds to the carbocation. · Net result is addition to the double bond

Classification Primary: carbon with -OH is bonded to one other carbon. Secondary: carbon with-OH is bonded to two other carbons. · Tertiary: carbon with-OH is bonded to three other carbons. Aromatic(phenol): -OH is bonded to a benzene ring

Spectroscopy is an analytical technique which helps determine structure. It destroys little or no sample. The amount of light absorbed by the sample is measured as wavelength is varied

Introduction Formula R-O-R where R is alkyl or aryl. Symmetrical or unsymmetrical Examples:

Discovery of Benzene Isolated in 1825 by Michael Faraday who determined C: H ratio to be 1: 1. Synthesized in 1834 by Eilhard Mitscherlich who determined molecular formula to be C6H6
