Oxidation and reduction of organic compounds
Write the chemical equation for the reaction that takes place when each alkene is mixed with H_{2} and Pt.
a. 1-butene
b. cis-2-butene
c. trans-2-pentene
Strategy
In the catalytic hydrogenation of an alkene, a hydrogen atom is added to each of the double-bonded carbon atoms and the double bond becomes a single bond. For a review of alkene naming, see Section 4.8.
