Which of the following compounds can undergo an E1 elimination reaction?

Step 1: Understand what an E1 elimination reaction is. It involves the removal of a leaving group (like bromine) and the formation of a double bond.
Step 2: Identify the compound in question, which is 2-bromobutane.
Step 3: Recognize that for an E1 reaction to occur, a stable carbocation must be formed after the leaving group departs.
Step 4: Determine the structure of 2-bromobutane. It has a bromine atom attached to the second carbon of a four-carbon chain.
Step 5: When bromine leaves, a carbocation is formed at the second carbon. Check if this carbocation is stable.
Step 6: Realize that the carbocation is secondary, which is relatively stable compared to primary or methyl carbocations.
Step 7: Conclude that since 2-bromobutane can form a stable secondary carbocation, it can undergo an E1 elimination reaction.
