Which of the following is an example of a good leaving group?

Explanation

In a chemical reaction, a leaving group is a molecular fragment that departs from the reactant molecule, taking with it a pair of electrons. A good leaving group is one that can stabilize the negative charge it carries after leaving, making it more stable and facilitating the reaction.Among the given options, Cl- (chloride ion) is a good leaving group because it is stable as an ion and can easily dissociate from the molecule, leaving behind a stable product. On the other hand, options B) OH (hydroxide ion), C) OR (alkoxide ion), and D) NH2 (amine group) are not as good leaving groups as they are less stable when carrying a negative charge.Therefore, the correct example of a good leaving group is Cl- (chloride ion).
