The Correct Option is A
Solution and Explanation
A nucleophile is a species that donates an electron pair to form a chemical bond in a reaction. The given species that can act as nucleophiles are: 1. NH3 (Ammonia)
2. PhSH (Phenyl thiol)
3. \({(H}_3{C}_2{S})_2\) (Dimethyl disulfide)
4. \({OH}^-\) (Hydroxide ion)
5. \({H}_3{O}^+\) (Hydronium ion)
6. \({NCH}_3\) (Methylamine) Thus, there are 6 nucleophiles in total.
