General rule, 2n-2, sp hybridization around the triple bond. The presence of the triple bond makes these very reactive. Aromatic hydrocarbons-all involve the molecule benzene C 6 H 6 . Aromatic compounds are very stable. Benzene molecules are very carcinogenic.
Addition reactions are a good test for a double bond.
A diatomic bromine solution of carbon tetrachloride is reacted with the suspected compound. Hydrocarbon Derivatives 1. Alcohols contain the hydroxide group, OH, substituted for hydrogen. Suffix is -ol. Hydrogen bonding in the -OH group causes alcohols to have a high boiling point.
