Which of the following is not an electrophile?
A) C2H5OC2H5
B) BF3
C) [CH3]3C(+)
D) HOCl
The correct answer is:
A) C2H5OC2H5 (diethyl ether)
Explanation: An electrophile is a species that accepts electron pairs during a chemical reaction. C2H5OC2H5 (diethyl ether) is a neutral molecule with no significant electron deficiency, so it does not readily accept electrons. In contrast, BF3, [CH3]3C(+), and HOCl are all electrophilic because they can accept electrons from nucleophiles.
