Question

Consider the reaction sequence given below :

Which of the following statements is true :

• A. Changing the concentration of base will have no effect on reaction $(1)$
• B. Changing the concentration of base will have no effect on reaction $(2)$
• C. Changing the base from $O{H}^{\ominus }$ to ${}^{\ominus }OR$ will have no effect on reaction $(2)$
• D. Doubling the concentration of base will double the rate of both the reactions

Answer 1

Answer: (A)

Reaction $1:S{N}_1$

Reaction $2:E_2$

$S{N}_1$ is independent of concentration of nucleophile/base
