Basic Organic

The decreasing order of nucleophilicity among the nucleophiles is

  1. 3, 2, 1, 4
  2. 4, 3, 2, 1
  3. 2, 3, 1, 4
  4. 1, 2, 3, 4

Answer

Strong bases are generally good nucleophile. If the nucleophilic atom or the centre is the same, nucleophilicity parallels basicity, i.e., more basic the species, stronger is the nucleophile. CN– is a better nucleophile than CH3O–

The correct option is A.
