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
