Question 2 16 pts H2S vs. H2O A Pair 1 B VS. в OH Pair 2 VS. CI (protic solvent) OH A vs. H2O Pair 3 B Pair 4 " CH,CH NH2 vs. CH.CH OH Pair 5 B (aprotic solvent) A Pair 6 B NH2 o vs. Pair 7 F vs. M Pair 8 B A B For each of the given pairs indicate which substance (A or B) will be a better nucleophile for SN2 reaction with CH3l by selecting the correct compound from the dropdown menu. Then select the chemical principle why that substance is a better nucleophile. Comparing Pair 1: Compound A is a better nucleophile dito r anti atom

plus state the reason why the following nucleophile is better nucleophile from the reasons given in pic.

Answer 1

Below I explained SN2 Nucleophilic factors and answers of your questions....
Answer :- *. A Nucleophile is a species that donates a Pair of electron to form new Covalent bond. *. Nucleophilicity is measured by comparing Rate of Reaction. * Faster the recution, the better the neccleophile 4 key factors contributing to nucleophilicity. 1. charge 2. Electronegativity 3. solvent 4. Steric hindrance 1 charge as an atom's Electron "Nudeophilicity Increased Density Increases." Example Hos H₂O 8t having charge It is Strony Nuclephête comparse to H2O Note: conjugate base is always a strong nucleophète. 2. Electronegativity: "Across the periodic table Nucleothelicity Increases with Decreusing Electronegativity's Example he > H₂N > Ho > F- Strong week Nudapphic Neccleophilic 3. solvent In Polar protic Solvents, Rudeophelicity Increases going down in the Periodic table. TO Box > FO poleg Protic solvent. Strong weak. St

Steric hindrance: least bulky compound is beet nulophele, Wheese as most bulky group is poor reelophite. oos too yoo. Here for our problem, Pair 1.
