Which of the following haloalkanes can undergo elimination to form an alkene? (2021)
Step 1: Identify the haloalkane in question, which is 2-bromobutane.
Step 2: Understand what elimination means. Elimination is a reaction where a molecule loses atoms or groups to form a double bond.
Step 3: Look for beta-hydrogens in the structure of 2-bromobutane. Beta-hydrogens are the hydrogens on the carbon atoms adjacent to the carbon that has the halogen (bromine in this case).
Step 4: Check the structure of 2-bromobutane. It has a bromine atom on the second carbon and hydrogens on the adjacent (beta) carbons.
Step 5: Confirm that there are beta-hydrogens available for elimination. Since 2-bromobutane has beta-hydrogens, it can undergo elimination.
Step 6: Conclude that 2-bromobutane can undergo elimination to form an alkene because it has the necessary beta-hydrogens.
