Consider the reaction sequence given below : Which of the following statements is true:

Consider the reaction sequence given below :

Which of the following statements is true:

Changing the base from ${OH}^{⊖}$ to ${}^{⊖}{OR}$ will have no effect on reaction $(2)$
Changing the concentration of base will have no effect on reaction $(1)$
Doubling the concentration of base will double the rate of both the reactions
Changing the concentration of base will have no effect on reaction $(2)$

Solution

First reaction is ${SN}^{1}$ in which rate does not depend on conc. of nucleophile.

Second reaction is $E 2$ reaction in which rate depends on conc. of base.
