One of the constituents of turpentine is a-pinene, formula C10 H16. The following scheme (called a “road map”) gives some reactions of...

In contact with a platinum catalyst, an unknown alkene reacts with three equivalents of hydrogen gas to give 1-isopropyl-...

1. Hydrohalogenation The reagent for this reaction is HX, where X is either Cl, Br or I. Product: Turn double bond into single and add X (halogen) to the MOST substituted carbon from the double bond (Markovnikov rule). Warning: Rearrangements are possible! hydrohalogenation predict the product The reaction is also called addition of hydrogen halides to alkenes. 2. Acid Catalyzed Hydration Of Alkenes The reagent is H2O with any catalytic acid such as H2SO4. Examples are: H2O/H
