Solution:

A nucleophile is a reagent that has an electron pair and will give it away. It is otherwise called a core cherishing reagent. Ex: NC–, OH–, R3C–(carbanions), and so on

An electrophile is a reagent which needs an electron pair and is otherwise called an electron-cherishing pair. Ex: Carbonyl gatherings, CH3CH2+(Carbocations), Neutral atoms (because of the presence of a solitary pair).
