Question

Given below are two statements: Statement I : The conversion proceeds well in the less polar medium. CH3–CH2–CH2–CH2–Cl – HO CH3–CH2–CH2–CH2–OH + Cl Statement II : The conversion proceeds well in the more polar medium. CH3–CH2–CH2–CH2–Cl N R3 CH3–CH2–CH2–CH2 –N–R R R + Cl In the light of the above statements, choose the correct answer from the options given below (A) Both Statement I and statement II are true (B) Statement I is false but statement II is true (C) Both statement I and statement II are false (D) Statement I is true but statement II is false

Answer: A

💡 Solution & Explanation

R3N + R–Br  R3N  R Br –   R3N – R + Br ֪–  Transition state Note that high polarity in transition state is favoured by polar solvent hence rate of reaction increses.
