Weba) Electrophiles are positively charged or neutral species having vacant orbitals. b) The electrophiles are attacked by the most electron-populated part of one nucleophile. c) Chemical species that do not satisfy the octet rule such as carbenes and radicals are electrophiles. d) Electrophiles are Lewis base. View Answer. WebTake home points on electrophiles: 1) They want electrons, meaning they are electron deficient, in order to form a new bond. 2) They are attacked by nucleophiles. 3) They are positively charged (or have a partial positive), polar and/or polarizable. 4) They become even better electrophiles in the presence of Lewis acids.
