Consider the following reactions : (a) (CH3)3CCH(OH)CH3 —conc. H2SO4→ (b) (CH3)2CHCH(Br)CH3 —conc. KOH→ (c) (CH3)2CHCH(Br)CH3 —(CH3)3O−K+→ (d) (CH3)2C(OH)CH2CHO —Δ→ Which of these reactions(s) will not produce Saytzeff product ?

1. (1) (d) only
2. (2) (c) only
3. (3) (b) and (d)
4. (4) (a), (c) and (d)

Correct answer: (1) (d) only

Solution

Reaction (d) involves dehydration of a secondary alcohol to form an aldehyde, which does not favor the formation of the more substituted alkene (Saytzeff product), thus it will not produce a Saytzeff product.
