Given below are two statements: Statement I: High concentration of strong nucleophilic reagent with secondary alkyl halides which do not have bulky substituents will follow S_N2 mechanism. Statement II: A secondary alkyl halide when treated with a larger excess of ethanol follows S_N1 mechanism. In the light of the above statements, choose the most appropriate from the options given below:

1. Statement I true but Statement II is false
2. Both Statement I and Statement II are true
3. Statement I is false but Statement II is false
4. Statement I is false but Statement II is true

Correct answer: Both Statement I and Statement II are true

Solution

Both statements are accurate because a strong nucleophile can facilitate an S_N2 reaction with secondary alkyl halides lacking bulky groups, while a secondary alkyl halide in a solvent like ethanol can undergo an S_N1 reaction due to the solvent's ability to stabilize the carbocation intermediate.
