We’re being asked to draw a Lewis structure for H3CNH2


To do so, we first need to do the following steps:

Step 1: Determine the central atom in this molecule.

Step 2: Calculate the total number of valence electrons present.

Step 3: Draw the Lewis structure for the molecule.



Step 1: C is less electronegative than N (EN = 4) and H can only form 1 bond so C is the central atom.


Step 2: The total number of valence electrons present  is:


            Group             Valence Electrons

N          5A                   1 × 5 e5 e

C          4A                   1 × 4 e4 e

H         1A                   5 × 1 e5 e

Total:  14 valence e


Step 3: 

The skeletal structure H3CNH2 gives us a clue on how the molecule is connected.
