What is the product of the E2 elimination of 2-bromobutane?

Step 1: Identify the starting molecule, which is 2-bromobutane. It has a bromine atom attached to the second carbon of a four-carbon chain.
Step 2: Understand that E2 elimination involves the removal of a bromine atom and a hydrogen atom from adjacent carbons to form a double bond.
Step 3: Locate the hydrogen atom that is on the carbon adjacent to the carbon with the bromine (the first carbon).
Step 4: Remove the bromine atom from the second carbon and the hydrogen atom from the first carbon simultaneously.
Step 5: When the bromine and hydrogen are removed, a double bond forms between the second and third carbons.
Step 6: The result of this elimination is 2-butene, which is the product of the reaction.
