Consider the following reaction Which of the following statements are correct ? a. I is the major product of the reaction b. II is the major product of the reaction c. Formation of I is in accordance with Saytzeff's rule d. II is more stable because it is more substituted

Options

  1. Aa,c
  2. Bb,c
  3. Ca,d
  4. Db,d

Correct answer

D. b,d

Step-by-step solution

- The reaction shown is a dehydrohalogenation of 2-bromobutane using alcoholic KOH. This is an elimination ( (E₂ )) reaction. - According to Saytzeff's rule, in an elimination reaction, the major product is the most substituted (most stable) alkene. - Product I is 1-butene, which is a monosubstituted alkene. - Product II is 2-butene, which is a disubstituted alkene. - Since II (2-butene) is more substituted than I (1-butene), it is also more stable and is therefore the major product. - Statement a is incorrect beca
