Question: Which of the following compounds undergoes elimination via an E2 mechanism?

Options:

  1. 2-bromopentane
  2. 2-bromo-2-methylpropane
  3. 1-bromobutane
  4. 3-bromopropanol

Correct Answer: 2-bromopentane

Solution: 

2-bromopentane can undergo E2 elimination because it has a beta-hydrogen available for elimination, while the others either do not or favor different mechanisms.

Questions & Step-by-Step Solutions

Which of the following compounds undergoes elimination via an E2 mechanism?
  • Step 1: Understand what E2 elimination means. E2 is a type of reaction where a base removes a hydrogen atom (beta-hydrogen) from a carbon adjacent to a carbon with a leaving group (like bromine).
  • Step 2: Identify the compound in the question, which is 2-bromopentane. This compound has a bromine atom (the leaving group) and adjacent carbon atoms that have hydrogen atoms (beta-hydrogens).
  • Step 3: Check if 2-bromopentane has beta-hydrogens. Look at the structure: the carbon with the bromine is connected to other carbons that have hydrogen atoms. Yes, it has beta-hydrogens.
  • Step 4: Compare with other compounds in the question. Determine if they have beta-hydrogens or if they favor different mechanisms (like E1 or substitution).
  • Step 5: Conclude that since 2-bromopentane has beta-hydrogens and a good leaving group, it can undergo E2 elimination.
