Current Question (ID: 10894)

Question:

$\text{An electrophile among the following is :}$

Options:

1. $\text{OH}^-$
2. $\text{NC}^-$
3. $R_3C^-$
4. $\text{Carbonyl group}$ (Correct)

Solution:

$\text{Hint: An electrophile is an electron seeking reagent.}$ $\text{Step 1:}$ $\text{In other words, an electron-seeking reagent is called an electrophile (E}^+\text{). Electrophiles are electron-deficient and can receive an electron pair. Carbocations (}CH_3CH_2^+\text{) and neutral molecules having functional groups such as the carbonyl group are examples of electrophiles.}$ $\text{Step 2:}$ $\text{A nucleophile is a reagent that brings an electron pair. In other words, a nucleus-seeking}$ $\text{For example : }\text{OH}^-, \text{NC}^-, \text{carbanions (}R_3C^-\text{), etc.}$ $\text{Neutral molecules such as }\text{H}_2\text{O}\text{ and an ammonia also act as nucleophiles because of the presence of lone pair.}$
