Which of the following is NOT a nucleophile?Select answer from the options belowNa+  H2O  Br-  HO-

Break Down the Problem

1. Identify and define what a nucleophile is.
2. Analyze each option to determine if it can act as a nucleophile.

Relevant Concepts

• A nucleophile is a chemical species that donates an electron pair to form a chemical bond in reaction. Nucleophiles are typically negative ions or molecules with lone pairs of electrons.

Analysis and Detail

1. Na+: This is a sodium ion, which has a positive charge and lacks an electron pair to donate. Therefore, it cannot function as a nucleophile.
2. H2O (water): Water can donate a lone pair of electrons and thus can act as a nucleophile.
3. Br- (bromide ion): This is a negatively charged ion with extra electrons, making it a strong nucleophile.
4. HO- (hydroxide ion): This ion carries a negative charge and has a lone pair, allowing it to act as a nucleophile.

Verify and Summarize

Among the options given, the analysis shows that Na+ does not have the ability to donate an electron pair, unlike the other species listed.

Final Answer

Na+ is NOT a nucleophile.
