nucleophilicity

Decreasing Order Of Nucleophilicity. Now, as we observe the atoms in the options, the atoms are in the same row of periodic tables. If the nucleophilic atom or the centre is same, more basic the species stronger is the nucleophile.

2, 3, 1, 4, i.e. Sh > oh > h 2 o > aco > p ho b. The decreasing order of nucleophilicity among the nucleophiles is 3, 2, 1, 4 4, 3, 2, 1 2, 3, 1, 4 1, 2, 3, 4
