COMEDK · Chemistry · 25. Haloalkanes and Haloarenes
Which of the following haloalkanes will give more than one isomeric product, on being heated with alc. KOH ?
- A 1- Chloro-2-methylbutane
- B 2- Chlorobutane.
- C 2-Chloro-3, 3-dimethylpentane
- D 1- Chloropentane.
Answer & Solution
Correct Answer
(B) 2- Chlorobutane.
Step-by-step Solution
Detailed explanation
Dehydrohalogenation of haloalkanes with alcoholic KOH follows Saytzeff rule, where the major product is the more substituted alkene. If multiple distinct \(\beta\)-hydrogens are available such that different alkenes can be formed, isomeric products are obtained. For…
