1. We will be doing the following reactions. Draw the reactions as Snl or Sn2 reactions including reaction arrows. RFR + Nal → R R + NaBr(s) acetone R PT R EtOH AgNOR OEt R + AgBr(s) + HNO3 2. We will be using Nal (in acetone) and ethanol as nucleophiles. Nat is a spectator ion. Classify I and ethanol as good nucleophiles or poor nucleophiles. Explain why. 3.

Hi, I have a question regarding SN1 and SN2 reactions: Using curved arrow formalism, draw out the mechanisms for these two reactions: 1. The SN1 reaction between t-bromobutane and 1% ethanol AgNO3 2. The SN2 reaction between 1-chlorohexadecane and 18% NaI in acetone Thanks!

Two separate reactions are conducted as outlined below. Reaction 1: 4 drops of benzyl chloride in 2 mL of 1% AgNO3 in ethanol. Reaction 2: 4 drops of 2-chlorobutane in 2 mL of 1% AgNO3 in ethanol. List the expected rate of each of the reactions. List the slowest reaction first and fastest reaction last. Explain your reasoning based on substrate structure, the nature of the leaving group (if applicable), and whether the conditions favor SN1 or SN2 mechanisms. (NOTE:...
