Question
Electrophile and nucleophile
✓
Answer
Electrophile:
1. Electrophile is an electron deficient species.
2. It is attracted towards negative charge (electron seeking).
3. It attacks a nucleophilic centre in the substrate and brings about an electrophilic reaction
4. It is an electron pair acceptor. (Lewis acid)
5. It can be a positively charged ion or a neutral species having a vacant orbital.
e.g. $H ^{+}, Br , NO _2^{+}, BF _3, AlCl _3$, etc.

Nucleophile:
- Nucleophile is an electron rich species.
- It is attracted towards positive charge (nucleus seeking).
- It attacks the electrophilic centre in the substrate and brings about a nucleophilic reaction.
- It is an electron pair donor. (Lewis base)
- It can be negatively charged ion or neutral species having at least one lone pair of electrons.
