Question
Which of the following is correct concerning a nucleophilic substitution reaction on an organic substrate (substitution on C atom)? Select one: A. leaving group is the Nucleophile and entering group is the Electrophile. OB. The entering group is the Nucleophile and the carbon bearing the leaving group is the Electrophile. OC. entering group is the Electrophile and carbon bearing the leaving group is the Nucleophile. D. carbon bearing the leaving group is the Nucleophile and the leaving group is the Electrophile.Explanation / Answer
Option B is correct
The entering group is the Nucleophile and the carbon bearing the leaving group is the electrophile is correct.
Explanation: carbon atom bearing leaving group is electrophile because the halide ion leaves the substrate with a lone pair of electrons by leaving an empty orbital on carbon atom which makes it electrophile. The electron rich species atatcks the electron deficient electrophile, the electron rich specis is called nucleophile. so the entering group is nucleophile.
