Questions & Step-by-Step Solutions
Which of the following compounds is most likely to undergo an E1 reaction?
Step 1: Understand what an E1 reaction is. E1 stands for unimolecular elimination, which is a type of reaction where a molecule loses a leaving group and forms a double bond.
Step 2: Identify the compounds given in the question. Look for the one that can form a stable carbocation.
Step 3: Recognize that tertiary carbocations (where the carbon is attached to three other carbons) are more stable than secondary or primary carbocations.
Step 4: Check the structure of 3-bromobutane. It has a tertiary carbon that can form a stable carbocation when the bromine leaves.
Step 5: Compare 3-bromobutane with other compounds. If they form less stable carbocations, they are less likely to undergo an E1 reaction.
Step 6: Conclude that 3-bromobutane is the best candidate for an E1 reaction because it forms a stable tertiary carbocation.
