For the following reactions where, k s and k e , are respectively, the rate constants for substitution and elimination, and μ = k s k e , the correct option is ________
Options
- Aμ B > μ A and k e A > k e B
- Bμ A > μ B and k e B > k e A
- Cμ B > μ A and k e B > k e A
- Dμ A > μ B and k e A > k e B
Correct answer
B. μ A > μ B and k e B > k e A
Step-by-step solution
(B) with more steric crowding forms elimination product compared to substitution K e ( B ) > K e ( A )   μ B = K s ( B ) K e ( A ) < μ A = K s ( A ) K e ( A )
