Question
The Cope rearrangement is a [3, 3]-sigmatropic rearrangement of one of these molecules. For 10 points each:
[10h] Name these molecules. In one reaction, groups at the 2 and 5 position of one of these molecules are on the same side of the ring as an EWG in the endo transition state.
ANSWER: dienes [accept diolefins]
[10m] The endo transition state is favored in the Diels-Alder reaction, a [4+2] [four plus two] example of this type of reaction where two components form a ring and decrease the bond multiplicity.
ANSWER: cycloaddition [prompt on addition reaction or pericyclic reaction]
[10e] The Diels-Alder reaction can be catalyzed with these proton-donating molecules. Solutions with these molecules have a pH below 7.
ANSWER: acids
