Since nucleophilies are Lewis base (Electron pair donors). Hence option D is wrong.
Remaining all are correct.

Which of the following statements is incorrect description of electrophiles? Question 1 options: Electrophiles contain large electron density. Combination of nitric acid and sulfuric acid can generate a strong electrophile. Electrophiles lack electron density. Electrophiles are attracted to negatively charged atoms. Question 2 (1 point) 3-Nitro methyl benzoate is more reactive toward electrophilic aromatic substitution reactions than methyl benzoate. Question 2 options: True False Question 3 (1 point) Predict the carbon atom that carries greatest partial negative charge.
