what are electrophiles?

dear sandeep

 an electrophile (literally electron-lover) is a reagent attracted to electrons that participates in a chemical reaction by accepting an electron pair in order to bond to a nucleophile. Because electrophiles accept electrons, they are Lewis acids (see acid-base reaction theories). Most electrophiles are positively charged, have an atom that carries a partial positive charge, or have an atom that does not have an octet of electrons. The electrophiles attack the most electron-populated part of a nucleophile. The electrophiles frequently seen in the organic syntheses are cations such as H+ and NO+, polarized neutral molecules such as HCl, alkyl halides, acyl halides, and carbonyl compounds, polarizable neutral molecules such as Cl2 and Br2, oxidizing agents such as organic peracids, chemical species that do not satisfy the octet rule such as carbenes and radicals, and some lewis acids such as BH3 and DIBAL.

electrophiles are electron loving species . They attract the negetive charged species towards themselves . for eg: cl- ,  bf3 etc.

electrophiles is derieved from electro meaning electrons and phile meaning loving...

so, an electrophile is an electron loving particle... usually an positivly charged species..

eg.. H⁺ NO⁺ etc..

as said by joshn electropliles are electron loving speacies  but not -ve  charged means they might  be +ve charged  speacies or neutral speacies with vacant orbitals
