The molecular formula $\text{CH}_3$ may correspond to an anion, a cation or a free radical. A species with the molecular formula $\text{CH}_3$ can behave as an electrophile, a free radical or a nucleophile, depending on how many outer shell electrons are on the central carbon atom. How many outer shell electrons must the central carbon atom have for $\text{CH}_3$ to behave in each of these ways?
- Aelectrophile: 6, free radical: 7, nucleophile: 8
- Belectrophile: 6, free radical: 8, nucleophile: 7
- Celectrophile: 7, free radical: 6, nucleophile: 8
- Delectrophile: 8, free radical: 7, nucleophile: 6
