After C—C Bond Formation... + OPP OPP The carbocation can lose a proton to give a double bond. –H + After C—C Bond Formation... OPP This compound is called geranyl pyrophosphate. It can undergo hydrolysis of its pyrophosphate to give geraniol (rose oil). After C—C Bond Formation... OPP OH Geraniol H 2 O.

Elimination Reactions

The E2 and E1 mechanisms differ in the timing of bond cleavage and bond formation, analogous to the S N 2and S N 1 mechanisms. E2 and S N 2 reactions have some features in common, as do E1 and S N 1 reactions. Base removes a proton from the β-carbon atom, while the halogen atom leaves from the α-carbon resulting in the formation of a π-bond ...
