Orgo Lab experiment: Isomerization of Carvone 1. Carvone contains a ketone and two double bonds. However, when treated with the concentrated acid only one reacts to create the carbocation. Which alkene reacts to form the carbocation and why only the one? 2. After the carbocation rearranges an elimination occurs, the alkene formed is a trisubstituted instead of the tetrasubstituted alternative. Why is this odd and what is the driving force for this specific alkene formation? 3. Using the H NMR...

For each of the following reactions, determine which ELIMINATION mechanism (E1 or E2) will occur. Alkyl Halide Substitution: Methyl 1° 2° 3° Base Strength: Strong Weak Mechanism Type: E1 E2 Draw the mechanism that leads to ALL products for the reaction. Finally, underline the major product of the elimination reaction: H3C OH H2C H2C1 Br CHE

Tertiary alcohols undergo elimination via an E1 mechanism since the tertiary carbocation intermediate is especially stable. Zaitsev's rule is followed in the elimination to give the more substituted alkene as the major product Draw curved arrows to show the movement of elections in this step of the mechanism
