Q. Which of the following is an electrophile?
A) $H_{2}O$
B) $SO_{3}$
C) $NH_{3}$
D) ROR
Explanation
(b)
The species which are electron deficient and accept a pair of electron are called electrophile. Hence, $SO_{3}$ is a electrophile as it contains an electron deficient centre. While $H_{2}O,\ NH_{3}\ and\ R - O - R$ are nucleophiles.
