During nucleophilic substitution, various species act as Lewis bases to attack the electrophilic carbon. Which of the following cannot act as a nucleophile?
Q1. During nucleophilic substitution, various species act as Lewis bases to attack the electrophilic carbon. Which of the following cannot act as a nucleophile?
Answer: H3O+
Explanation: Nucleophiles are electron-rich species with lone pairs or negative charges. H3O+ is tempting but it is a cation and acts as an electrophile.
