Question: Which of the following compounds undergoes elimination to form an alkene most readily?

Options:

  1. 1-bromopropane
  2. 2-bromopropane
  3. 3-bromopropane
  4. 1-bromo-2-methylpropane

Correct Answer: 3-bromopropane

Solution:

3-bromopropane undergoes elimination more readily due to the stability of the tertiary carbocation formed during the reaction.

Questions & Step-by-Step Solutions

Which of the following compounds undergoes elimination to form an alkene most readily?
  • Step 1: Understand what elimination means. Elimination is a chemical reaction where atoms or groups are removed from a molecule, often forming a double bond (alkene).
  • Step 2: Identify the compounds given in the question. We need to compare them to see which one can easily lose atoms/groups.
  • Step 3: Know about carbocations. A carbocation is a positively charged carbon atom. The stability of this carbocation affects how easily elimination can happen.
  • Step 4: Recognize that tertiary carbocations (where the carbon is connected to three other carbons) are more stable than secondary or primary carbocations.
  • Step 5: Determine which compound forms a tertiary carbocation upon elimination. In this case, 3-bromopropane forms a tertiary carbocation.
  • Step 6: Conclude that since 3-bromopropane forms a stable tertiary carbocation, it undergoes elimination to form an alkene more readily than the others.
