NEET 2020 Phase 1 Chemistry - Haloalkanes and Haloarenes Question 14 English Explanation


Since β\beta β-hydrogen is abstracted it is β\beta β-elimination.
Since more substituted alkene is formed (stable and major product), it follows Zaitsev's rule or Saytzev's rule.
Since H and Br are removed, it is dehydrohalogenation.
