The correct order of nucleophilicity is
Options
- AF - > OH -
- BH 2 O ¨ > OH -
- CROH > RO -
- DNH 2 - > NH 3
Correct answer
D. NH 2 - > NH 3
Step-by-step solution
Nucleophilicity is directly proportional to the electro density on donor atom and the size of donor atom (in gas) And Stronger the base, greater the nucleophilicity. As weak acid will have a strong conjugate base NH 2 -     is stronger base than ammonia.Hence, NH 2 - is a stronger nucleophile than ammonia
