Questions & Step-by-Step Solutions
Which of the following haloalkanes is most likely to undergo elimination rather than substitution? (2020)
Step 1: Understand the difference between elimination and substitution reactions. Elimination reactions remove atoms to form a double bond, while substitution reactions replace one atom with another.
Step 2: Identify the structure of the haloalkanes given in the question. Focus on the one that has a branched structure.
Step 3: Recognize that branched haloalkanes, like 3-bromobutane, have steric hindrance, which makes it harder for nucleophiles to attack and replace the halogen.
Step 4: Realize that in the presence of steric hindrance, elimination reactions are favored because they can occur without the need for a nucleophile to attack the carbon directly.
Step 5: Conclude that 3-bromobutane is more likely to undergo elimination rather than substitution due to its branched structure and steric hindrance.
