Question

E1 reactions are more or less useful than E2.

A) E1 reactions are irrelevant
B) E2 reactions are irrelevant
C) E1 reactions are more useful than E2
D) E1 reactions are less useful than E2.

Answer 1

E1 reactions and E2 reactions are both types of elimination reactions in organic chemistry. E1 reactions are unimolecular elimination reactions that occur when a carbocation intermediate is formed. E2 reactions are bimolecular elimination reactions that occur when a strong base removes a proton from a carbon adjacent to a leaving group.

Step-by-step explanation:

E1 reactions and E2 reactions are both types of elimination reactions in organic chemistry. E1 reactions are unimolecular elimination reactions that occur when a carbocation intermediate is formed. E2 reactions are bimolecular elimination reactions that occur when a strong base removes a proton from a carbon adjacent to a leaving group.

In terms of usefulness, it depends on the specific reaction and starting materials. E1 reactions are more likely to occur with tertiary substrates, while E2 reactions are more likely to occur with secondary substrates. Primary and methyl substrates tend to favor substitution reactions (SN2) instead of elimination reactions. So, the answer to your question is D) E1 reactions are less useful than E2.
