JEE MAIN - Chemistry (2020 - 2nd September Evening Slot - No. 21)

Consider the reaction sequence given below:

Which of the following statements is true?

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

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

Changing the base from OH^- to ^-OR will have no effect on reaction (2)

Doubling the concentration of base will double the rate of both the reactions

Explanation

For reaction 1,
rate = K [t-BuBr] ....(1)

for reaction 2,
rate = K[t-BuBr][OH^–] ...(2)

Reaction 1 is independent of concentration of OH^– where as reaction 2 is dependent on concentration of OH^–

Hence changing the concentration of base will have no effect on reaction 1.
