Q: Which of the following statements is true regarding the E1 mechanism?
Solution: E1 reactions involve the formation of a carbocation intermediate, followed by deprotonation to form the alkene.
Steps: 5
Step 1: Understand that E1 stands for 'unimolecular elimination' reaction.
Step 2: Recognize that E1 reactions start with the loss of a leaving group from a substrate, which creates a carbocation (a positively charged carbon ion).
Step 3: Identify that the formation of the carbocation is the first step and is the rate-determining step of the E1 mechanism.
Step 4: After the carbocation is formed, a base removes a proton (H) from a neighboring carbon atom.
Step 5: The removal of the proton leads to the formation of a double bond, resulting in the creation of an alkene.
