NEET · Chemistry · STD 12 - 6. Haloalkanes and Haloarenes
Elimination reaction of \(2 -\)Bromo-pentane to form pent\(-2-\)ene is: \((a)\) \(\beta\) \(-\)Elimination reaction \((b)\) Follow Zaitsev rule \((c)\) Dehydrohalogenation reaction \((d)\) Dehydration reaction
- A \((a),(b),(d)\)
- B \((a),(b),(c)\)
- C \((a),(c),(d)\)
- D \((b),(c),(d)\)
Answer & Solution
Correct Answer
(B) \((a),(b),(c)\)
Step-by-step Solution
Detailed explanation
This reaction is an example of \(\beta\) \(-\)elimination. Hydrogen is removed from \(\beta\) \(-\)carbon and halgoen from \(\alpha\) \(-\)carbon, hence, dehydrohalgoenation reaction. Generally in \(E2\) reaction Zaitsev alkene is formed
