**Title: Factors Influencing SN2 Reactions****Question:**Which of the following is a correct factor influencing SN2 reactions?1) Having a chlorine on the alkyl halide decreases the rate of the SN2 reaction as compared to the presence of a fluorine on the alkyl halide.2) Protic solvents decrease the speed of an SN2 reaction.3) Using tertiary halides as substrates increases the rate of SN2 reactions.4) High temperatures increase the rate of SN2 reactions.**Analysis:**- **Option 1:** Discusses the role of halogens in SN2 reactions, comparing the effects of chlorine and fluorine substitutions. - **Option 2:** Focuses on the impact of protic solvents on the speed of SN2 reactions. Protic solvents can stabilize intermediates or transition states, often leading to decreased reaction rates. - **Option 3:** Considers the effect of substrate structure, specifically tertiary halides, on SN2 reaction rates. Due to steric hindrance, tertiary substrates typically slow down SN2 reactions. - **Option 4:** Examines the influence of temperature on reaction rates. Higher temperatures generally increase the rate of chemical reactions, including SN2 reactions.

Second option (2) Protic solvents decrease the speed of an SN2 reaction.
