Question

Which of the following sets of groups contains only electrophiles?

• A. $NH_{2}^{-},NO_{2}^{+},H_{2}O,NH_{3}$
• B. $F^{-},OH^{-},NH_{3}SO_{3}$
• C. $NO_{2}^{+},AlCl_{3},SO_{3},CH_{3}\overset{+}{C} = = O$
• D. $NH_{3},BF_{3}AlCl_{3},H_{2}O$

Answer 1

Answer: (C)

$NO_{2}^{+},AlCl_{3},SO_{3},CH_{3}\overset{+}{C} = = O$

Answer 2

$NO_{2}^{+},AlCl_{3},SO_{3}$ and $CH_{3}\overset{+}{C} = = O$ are electrophiles.
