True Or False Nucleophile Questions?

Question

Compared to Cl− or Br−, in the 2-butanol reaction,

a. H2O is a relatively good nucleophile, because it had to be avoided during the workup procedure.
b. H2O is a relatively poor nucleophile, because no or very little alcohol is observed in the GC.
c. H2O is a relatively poor nucleophile, because it carries no negative charge.
d. H2O is a relatively good nucleophile, because the yield of halides was low due to back-reaction with water.

Answer 1

H2O is a relatively poor nucleophile because it doesn't have a charge.
