Consider the following reactions (1) (CH 3 ) 3 CCH(OH)CH 3 → conc .H 2 SO 4 (2) (CH 3 ) 2 CHCH(Br)CH 3 → conc . KOH (3) ( CH 3 ) 2 CHCH(Br)CH 3 → (CH 3 ) 3 CO ⊖ K ⊕ (4) Which of these reactions(s) will produce Saytzeff product?

Options

  1. A(1), (2) and (4)
  2. B(3) only
  3. C(4) only
  4. D(2) and (4)

Correct answer

A. (1), (2) and (4)

Step-by-step solution

Bulky base like ( C H 3 ) 3 O ⊖ K ⊕ always prefers Hoffmann product (less stable alkene) in case of 1, 2 and 4 elimination product are according to Saytzeff Rule (more stable alkene)
