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.
Answer:
It is a model of the atom that has electrons surrounding the nucleus
Step by step explanation:
Answer: There are four atoms
Explanation: mass of Cl atom is 35.45 amu
Amount of atoms n = m/M = 142 / 35.45 = 4
