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

Options

  1. AChanging the base from OH ⊖ to OR ⊖ will have no effect on reaction ( 2 )
  2. BChanging the concentration of base will have no effect on reaction ( 1 )
  3. CDoubling the concentration of base will double the rate of both the reactions
  4. DChanging the concentration of base will have no effect on reaction ( 2 )

Correct answer

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

Step-by-step 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.
