Which statement about a methyl functional group is correct? 1) a methyl group consists of a carbon bonded of three hydrogen atoms 2) a methyl group is polar 3) a methyl group may be negatively charged

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

Explanation:

This is the answer your teacher probably expects.

Technically, however, all three are correct.

2) A C atom is slightly more electronegative than an H atom, so a methyl group is slightly polar. The polarity is so small that we usually call the methyl group nonpolar.

3) The C atom is at the negative end of the group dipole, but the charge is so small that we usually consider it to be zero.
