Given below are two statements: In the light of the above statements, choose the correct answer from the options given below
- Statement I is false but Statement II is true
- Statement I is true but Statement II is false
- Both Statement I and Statement II are false
- Both Statement I and Statement II are true
Answer
(4) Both Statement I and Statement II are true
Solution
Effect of polarity: compare charge in reactants and in transition state (TS).
I: HO- (localised charge) TS (charge dispersed) polar solvent stabilises reactant more, raises Ea faster in less polar medium (true).
II: neutral R3N TS with developing charges polar solvent stabilises TS, lowers Ea (true).
Answer: (4)
