Question

Which reactant in each of the following pairs is more nucleophilic? Explain.a. -NH2 or NH3b. H20 or CH3CO2-c. BF3 or F-d. (CH3)3P or (CH3)3Ne. I- or Cl-f. -C triple bonded to N or -OCH3

Answer 1

Answer:

I^- or Cl^-

Explanation:

A nucleophile is any reagent that donates an unshared pair of electrons to form a new covalent bond. Nucleophiles are mostly bases also. Nucleophilicity is a kinetic property, it refers to the rate at which a nucleophile replaces a leaving group from an alkyl halide.

Looking at the options, Cl^- and I^- are the best nucleophiles among the options provided in the question.
