Q.
Pick out the electrophiles from following species
$B F_{3}, N H_{3}, M e_{3} C^{\oplus}, H C l$
AMUAMU 2013Organic Chemistry – Some Basic Principles and Techniques
Solution:
The neutral or positively charged species with deficiency of electrons and capable of accepting a pair of electrons (Lewis acid) are called electrophiles, e.g., $B F_{3}$ and $M e_{3} C \oplus$.
