An electrophile is a species that
Correct answer: B. accepts a pair of electrons and is attracted to electron rich centres
- A. donates a pair of electrons
- B. accepts a pair of electrons and is attracted to electron rich centres
- C. always carries a negative charge
- D. contains an unpaired electron
Explanation
Electrophile means electron loving, so such a species is electron deficient and attacks regions of high electron density such as a double bond, examples being NO2+ and the polarised bromine molecule. A nucleophile does the opposite, donating a lone pair to an electron poor carbon. A species with an unpaired electron is a free radical, a third category altogether.

About Classification of Organic Compounds
Organic compounds are classified by carbon skeleton into open-chain, branched-chain and cyclic compounds, including homocyclic and heterocyclic types. The classification also uses functional groups to distinguish hydrocarbons, halo compounds, alcohols, aldehydes, ketones, carboxylic acids and their derivatives, which is different from naming compounds by IUPAC rules.
