A methyl group may be negatively charged.

The correct statement about a methyl functional group is:

A methyl group consists of a carbon bonded to three hydrogen atoms.

A methyl group is represented as -CH₃, which indeed consists of one carbon atom bonded to three hydrogen atoms.

The other statements are not correct:

  • A methyl group is not polar; it is nonpolar due to the similar electronegativities of carbon and hydrogen.
  • A methyl group typically does not carry a negative charge under normal circumstances; it is a neutral group (though it can participate in reactions that might lead to a charged state in specific circumstances, it is not inherently negatively charged).
