Question

Pick out the electrophiles from following species $BF_{3}$ , $NH_{3}$ , $Me_3C^+$ , $HCl$

• A. $BF_3$ and $NH_3$
• B. $Me_{3}C^+$ and $HCl$
• C. $BF_3$ and $Me_3C^+$
• D. $NH_3$ and $HCl$

Answer 1

Answer: (C)

$BF_3$ and $Me_3C^+$

Answer 2

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., $BF_3$ and $Me_3C?$.
