Question

Consider the reaction sequence given below :

Which of the following statements is true:

(1) Changing the concentration of base will have no effect on reaction (1)

(2) Doubling the concentration of base will double the rate of both the reactions

(3) Changing the concentration of base will have no effect on reaction (2)

(4) $^\Theta$OR will have no effect on reaction (2)

Answer 1

Ans : (1) Changing the concentration of base will have no effect on reaction (1)

Explanation :

Reaction 1 : SN₁

Reaction 2 : E₂

SN₁ is independent of concentration of nucleophile/base.
