Which of the following is good leaving group?
Correct answer: A. NH2-
- A. NH2-
- B. HSO4-
- C. OR-
- D. OH-
Explanation
This is the best-leaving group among the options given. When NH2- leaves a reaction intermediate, it becomes neutral ammonia (NH3), which is quite stable due to its complete octet. The negative charge on NH2- is distributed over two electronegative nitrogen atoms, making it a good leaving group. Therefore, option a is correct.

About Alkyl Halides
Alkyl halides are named and related to their carbon-halogen structure, polarity and reactivity. The key reactions are nucleophilic substitution by SN1 and SN2 mechanisms and elimination by E1 and E2 mechanisms, including how substrate structure, nucleophile, base, solvent and temperature influence substitution versus elimination.
