What is an electrophile in organic chemistry?

An electrophile is an electron-deficient species that accepts electron pairs from nucleophiles to form chemical bonds.

Think of an electrophile like a magnet that is missing some pieces and really wants electrons to feel complete; it could be a positively charged ion, a molecule with a positively polarized atom, or a compound with a bond that can pull electrons away, and it reacts by accepting an electron pair from a nucleophile which has extra electrons to share. When two atoms form a bond, the nucleophile donates an electron pair and the electrophile accepts it, so the bond forms where the electron pair ends up being shared. Electrophiles are important in many organic reactions like addition and substitution, and their strength depends on how electron-poor the atom is and how well it can stabilize any positive charge that results. You can often spot an electrophile if an atom has a positive formal charge or is attached to electronegative atoms that pull electron density away.

A common mistake is thinking that only positively charged species are electrophiles, when in fact neutral molecules with polarized bonds can also act as electrophiles, so look for electron-poor centers rather than just charges. Another misconception is believing that electrophiles always attack randomly; they actually react at the site of highest positive character or where forming the bond will be most stable, so consider resonance and inductive effects to predict the site. A practical tip is to draw resonance structures and partial charges to identify where the electrophile will accept electrons, which makes predicting reactions much easier.
