Explanation
Nucleophiles are electron-rich species that donate a pair of electrons. Options A (C2H5O⁻), B (SCN⁻), and C (NH3) all have lone pairs or negative charges, making them nucleophilic. However, option D (CH3⁺) is a positively charged carbocation and lacks electron density, so it cannot act as a nucleophile.
