Questions & Step-by-Step Solutions
Which of the following haloalkanes will undergo elimination reaction most readily?
Correct Answer: 2-bromopropane
Step 1: Understand what haloalkanes are. Haloalkanes are organic compounds that contain carbon, hydrogen, and halogen atoms (like bromine).
Step 2: Know what an elimination reaction is. An elimination reaction is a chemical reaction where two atoms or groups are removed from a molecule, resulting in the formation of a double bond.
Step 3: Identify the haloalkanes given in the question. In this case, we are focusing on 2-bromopropane.
Step 4: Recognize that 2-bromopropane has a bromine atom attached to the second carbon of a three-carbon chain (propane).
Step 5: Understand that for elimination to occur, the molecule needs to form a stable alkene. Alkenes are more stable when they are more substituted (have more carbon groups attached to the double bond).
Step 6: Realize that 2-bromopropane can form a double bond between the second and third carbon when the bromine is removed, resulting in a stable alkene (propene).
Step 7: Conclude that 2-bromopropane undergoes elimination readily because it forms a stable alkene.
