Distinguish between Electrophile and nucleophile.

Solution

No. Electrophile Nucleophile
1. An electrophile is an electron-deficient species. A nucleophile is an electron-rich species.
2. It is attracted towards negative charges (electron seeking). It is attracted towards a positive charge (nucleus seeking).
3. It attacks a nucleophilic center in the substrate and brings about an electrophilic reaction It attacks the electrophilic center in the substrate and brings about a nucleophilic reaction.
4. It is an electron pair acceptor. (Lewis acid) It is an electron-pair donor. (Lewis base)
5. It can be a positively charged ion or a neutral species having a vacant orbital. It can be negatively charged ion or neutral species having at least one lone pair of electrons
6. e.g. H+, Br+,\[\ce{NO^+_2}\], BF3, AlCl3, etc. e.g. OH-, Cl-, CN-, etc.
