The nucleophilicity of the five different oxygen functional groups (carboxyl, diketone, ketone, lactone, and quinone) on the graphene are evaluated by DFT calculations. Two different methods are employed to obtain three different reactivity descriptors, namely, sk−, wk−, and sk−/sk+. The calculations indicate that the quinone group is the most nucleophilic site among the investigated ones. The diketone...
