Organic chemistry

The formula CH₃ can represent an anion, a cation or a free radical. Species with molecular formula CH₃ can act as an electrophile, a free radical or a nucleophile depending on the number of outer shell electrons on the central carbon atom. How many outer shell electrons must be present for CH₃ to act in these different ways ?

• B

• C

• D
