Electrophile :- ELECTRO + PHILLIC
| |
electron loving
(-ve charge)
electrophile means negative center loving species.
the species that can accept an electron pair is known as electrophile.
How to identified a electrophile:
1. all simple cation is electrophile ( H⁺,Br⁺,NO⁺ etc)
2. The species with vacant d- orbital in central atom (PCl₃,SF₆
3. All halogens
4. atoms with sextet (O,S, Se etc)
(b)NUCLEOPHILE : NUCLEO + PHILE
| |
nucleus loving
(+ve charge)
thus, positive center loving species are known as nucleophile.
the species that can give a lone pair of electron is known as nucleophile.
How to identified nucleophile :
1. usually anions are nucleophile (NH₂⁻,OH⁻,CH₃⁻ etc)
2. the species having lone pair on the central atom are nucleophiles.(NH₃,H₂O,ROH etc)
