This is the CH3NH2 Lewis structure.
Methylamine.  For Methylamine we we have 14
valence electrons.  For organic compounds
they are often written the
way that you should place the atoms on
your Lewis structure.
So we'll put the carbon here and the
Nitrogen,
and we can see that there are three
Hydrogens on the
carbon ...  and then two
on the nitrogen.  We'll put two electrons
between the atoms to form
chemical bonds. And we've used at this
point 12 valence electrons.
We'll put the last two on the Nitrogen.
So at this point all the hydrogens have
two valence electrons,
so their outer shells are full. The carbon has
eight
and then the nitrogen has eight as well. And
we've only used 14 valence electrons.
So this is the Lewis structure for CH3NH2, Methylamine,
and this is Dr. B.  Thanks for watching.
