Understand the Problem
The image contains exam questions from a chemistry course, asking for explanations of various organic chemistry reactions, mechanisms, and properties of compounds.
Answer
Detailed explanation on SN1 and SN2 reactions, mechanisms, and factors.
The final answer is a detailed explanation on SN1 and SN2 reactions including their mechanisms and factors affecting them, as discussed in sources.
Answer for screen readers
The final answer is a detailed explanation on SN1 and SN2 reactions including their mechanisms and factors affecting them, as discussed in sources.
More Information
SN1 reactions involve a two-step mechanism with a carbocation intermediate, while SN2 reactions occur in one step with a concerted mechanism. Factors include the structure of the substrate, strength of the nucleophile, and the solvent.
Tips
Always consider the stability of intermediates and the steric hindrance when determining which mechanism is likely. Misunderstanding these can lead to incorrect predictions of reactions.
