Which of the following is not nucleophilic?
A)A proton
B)A carbanion
C)An imidazole
D)A hydroxide
E)A carboxylic acid

Question

Quizplus · Accepted Answer

A proton is not nucleophilic because it is a positively charged species and cannot donate electron density to another molecule. The other choices are nucleophilic because they can donate electron density - a carbanion has a negative charge, an imidazole has a lone pair of electrons, a hydroxide ion has a negative charge and a lone pair of electrons, and a carboxylic acid has a carbonyl group which can accept electrons, making the oxygen atom more negative and nucleophilic.
