Q.
Which of the following is not an electrophile?
Organic Chemistry – Some Basic Principles and Techniques
Solution:
It is a nucleophile on which an electrophile attack as:
$\underset{\text{Nucleophile}}{CH _{2}= CH _{2}}+ \underset{\text{Electrophile}}{H ^{+}} \longrightarrow CH _{3}-\overset{+}{ C}H _{2}$
All others are electrophile.
