WebSep 6, 2024 · These are strong nucleophiles because it’s attached to a metallic group Na+ so it’s automatically a negative anion. Is OCH3 a good nucleophile? An alkoxide molecule has more steric hindrance and less distinct polarization, making it less attracted to the positive carbon center. WebExplanation: Nucleophiles are rich in electron species that can form bonding electrophiles (electron-deficient species). Strong bases are strong nucleophiles on the other hand … WebFeb 4, 2024 · Since the nucleophilic attack occurs via overlap of the nucleophile's HOMO with the p orbital of a carbon atom in the alkyl halide, the major factor in determining the nucleophilicity is how high the HOMO is (higher HOMO --> more nucleophilic).

An atom with a higher polarizability will share his electrons more easier since they are less attracted by the nucleus. The more the electrons are near the nucleus, the more it's hard the share them with an electrophile. I − is thus more nucleophile than F −.
