Which of the following statements is true regarding the E1 elimination mechanism?
  1. It involves a concerted mechanism.
  2. It proceeds through a carbocation intermediate.
  3. It is favored by strong bases.
  4. It results in stereospecific products.

Questions & Step-by-Step Solutions

Which of the following statements is true regarding the E1 elimination mechanism?
  • Step 1: Understand that E1 elimination is a type of chemical reaction.
  • Step 2: Know that E1 stands for 'unimolecular elimination'.
  • Step 3: Recognize that E1 elimination happens in two main steps.
  • Step 4: In the first step, a leaving group (like a halide) departs from the molecule, forming a carbocation (a positively charged ion).
  • Step 5: In the second step, a base removes a proton (H) from a neighboring carbon, leading to the formation of a double bond.
  • Step 6: Conclude that because it involves the formation of a carbocation, E1 is a two-step process.
