allerySaytzeff product from 2-bromo-3-methylbutane + base:
A1-pentene
B2-methyl-1-butene
C2-methyl-2-butene (more substituted, Saytzeff)
DMix
Answer & Solution
Correct answer: C. 2-methyl-2-butene (more substituted, Saytzeff)
**E2 of 2-bromo-3-methylbutane:** H removal from C3 gives 2-methyl-2-butene (trisubstituted alkene), Saytzeff.
H removal from C1 gives 3-methyl-1-butene (monosubstituted, Hofmann).
Saytzeff (more substituted) dominates with normal bases.
