💡 Solution & Explanation

# Characteristics of Electrophiles **Definition:** An electrophile is a species that seeks electrons and accepts electron pairs during a chemical reaction. **Analysis of each option:** **(1) Electron rich species** ✗ - Electrophiles are electron-*deficient*, not electron-rich. Electron-rich species are nucleophiles. **(2) Electron deficient species** ✓ - Electrophiles lack electrons and actively seek electron pairs from nucleophiles to complete their valence shell. - Examples: $BF_3$, $C^+$, $AlCl_3$ **(3) Complete octet** ✗ - Electrophiles have incomplete octets (or vacant orbitals). A complete octet would not attract electrons. **(4) Lewis base** ✗ - Lewis bases donate electron pairs; electrophiles *accept* them. This is the opposite property. **Answer: Option (2) — Electron deficient species** Electrophiles are characterized by their electron deficiency, which drives their attraction to electron-rich nucleophiles in organic and inorganic reactions.
