The formula $\text{CH}_3$ may denote 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 the central carbon atom has. 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
