Water is a protic polar solvent. The given options belong to the same group and nucleophilicity increases down the group in polar protic solvents. 13. For the following: (1) I– (2) Cl– (3) Br– the increasing order of nucleophilicity in polar protic solvent would be (a) I–< Br–< Cl– (b) Cl–< Br–< I– (c) I–< Cl–< Br– (d) Br–< Cl–< I– The given options belong to the same group and nucleophilicity increases down the group in polar protic solvents.
