Question
Which of the following is NOT a nucleophile?Select answer from the options belowNa+ H2O Br- HO-
Solution
The answer is Na+. A nucleophile is a species that donates an electron pair to an electrophile to form a chemical bond in a reaction. Na+ is a cation, meaning it has a positive charge due to a loss of electrons, so it cannot donate electrons and therefore is not a nucleophile. On the other hand, H2O, Br-, and HO- can all act as nucleophiles because they have lone pairs of electrons that can be donated.
