  • Nucleophiles and electrophiles are reaction intermediates having electron rich and electron deficient centres respectively.

Nucleophiles and electrophiles are reaction intermediates having electron rich and electron deficient centres respectively. Hence, they tend to attack electron deficient and electron rich centres respectively. Classify the following species as electrophiles and nucleophiles.
(i)H_{3}CO^{-} 

(ii) 


(iii) Cl^{.}

(iv)Cl_{2}C:

(v)(H_{3}C)_{3}C^{+}

(vi)Br^{-}

(vii)H_{3}COH

(viii)R-NH-R

Electrophiles can be defined as the electron seeking species or electron-deficient species. They can be either positively charged or neutral.

Therefore, the following species are electrophiles-

(iii) Cl^{.}

(iv)Cl_{2}C:

(v)(H_{3}C)_{3}C^{+}

electron rich species are called nucleophiles; they can be either negatively charged or neutral.

The following species are nucleophiles-

(i)H_{3}CO^{-} 

(ii) 

(vi)Br^{-}

(vii)H_{3}COH

(viii)R-NH-R
