$OH^{\Theta}$

Vedclass · Answer

(C) nucleophile is a species that donates an electron pair to an electrophile. In general,a negatively charged species is a better nucleophile than its conjugate acid because the negative charge increases the electron density on the donor atom. Comparing $H_2O$ and $OH^{\Theta}$,$OH^{\Theta}$ has a negative charge,making it a stronger nucleophile. Note: Options $B$ and $C$ are identical ($HO^{\Theta}$ and $OH^{\Theta}$ are the same species). Assuming the question intends to compare different species,$OH^{\Theta}$ is the correct choice.
