Where do 1°, 2°, and 3° alkyl substrates fit into Sn1 and Sn2 reactions?
gpt
1° is best in Sn2 and impossible in Sn1, 2° could be either, and 3° is impossible in Sn2 and best in Sn1.
Explanation: The degree of substitution of an alkyl halide influences its reactivity in Sn1 and Sn2 reactions due to factors like steric hindrance and carbocation stability.
