- ‘In the case of binary covalent compounds, the positive oxidation number is assigned to the more electropositive element, and the negative oxidation number to the more electronegative element.’
- ‘In this reaction the electrophile is produced when the methyl chloride reacts with the aluminum chloride to form an electropositive CH 3 group.’
