The correct statement regarding electrophile is :

1. Electrophile is a negatively charged species and can form a bond by accepting a pair of electrons from another electrophile
2. Electrophiles are generally neutral species and can form a bond by accepting a pair of electrons from a nucleophile
3. Electrophiles can be either neutral or positively charged species and can form a bond accepting a pair of electrons from a nucleophile
4. Electrophile is a negatively charged species and can form a bond by accepting a pair of electrons from a nucleophile
