Sketch the following molecule CH3NH2 skeletal structure H3C-NH2 including all hydrogen atoms and nonbonding electrons

To sketch the skeletal structure of CH₃NH₂, which is methylamine, we start with the basic layout of the molecule.

The molecule consists of a carbon (C) atom bonded to three hydrogen (H) atoms, and this carbon is also bonded to a nitrogen (N) atom. The nitrogen atom is then bonded to two additional hydrogen atoms. To represent this accurately:

• Draw a carbon atom (C) in the center.
• From the carbon atom, draw three lines outward towards three hydrogen atoms (H). This reflects the three H atoms bonded to the carbon.
• From the carbon atom, draw a line to the nitrogen atom (N).
• Then, connect two hydrogen atoms to the nitrogen atom. Since nitrogen can also have a lone pair of electrons, we can denote this by placing two dots (•) next to the nitrogen atom.

This structure should depict all hydrogen atoms and the nonbonding electrons on the nitrogen, giving a clear representation of methylamine’s skeletal formula. The final structure can be visually summarized as:

    H   H
     |   |
   H-C-N-H
     |   |
    H   •

Here, each line represents a bond, and the lone pair on nitrogen is indicated with dots. This accurately represents the molecular structure of CH₃NH₂.
