The formula $\text{CH}_3$ may stand for an anion, a cation, or a free radical. A species with 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 are needed 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
