A. C2H5O-
B. SCN-
C. NH3
D. H3C+
¨ H3C+ is not a nucleophile. A nucleophile is an atom or molecule that donates a pair of electrons to another atom or molecule, resulting in the formation of a new chemical bond. Nucleophiles are often negatively charged or contain lone pairs of electrons, which can be used to form new bonds with other atoms or molecules.
¨ In the given options, C2H5O-, SCN-, and NH3 are all nucleophiles because they contain negative charges or lone pairs of electrons that can be used to form new chemical bonds. H3C+, on the other hand, is a positively charged molecule that lacks lone pairs of electrons and is therefore not a nucleophile.
