For each of the following pairs of organic molecules, circle the one that would react with a given nucleophile at a faster rate in the Su2 reaction, and briefly explain your choice. amor

Answer 1

solution : 6 ② Het on us to Acetate aninon strong nucleophile than acetic acid because the electron density of acetate anion is more as compare to neutral acid. The electron density of acetate anion can easily ophile. So anion is good nucleophile than neutral molecuk. attack on electrophile. So anion is good nu (OscN vs % -cN sulphur anion more Auel strong nucleophile than oxygen anion because oxygen is mote more electro negative than sultur- Hence sulphur can donate electron more easily compared to oxygen CH2 O NH) usual 1 amine strung nucleophile than 3o amine because of steric hindranu of 3 amine- Even though 3° amine have 3-CH3 group that have ti effect and to amine have only one alkyl group but major reson is stene hindrance 05 too Alkoxide strong an nucleophile than phenoxide because electron pair on phenoxide oxygen atom involved in resonance and partially available for nucleophile or nucleophilic attack. Alkoxide electron density on oxygen to effect of alkyl group and easily available for nucleo- Philic attack.
