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 e– = 5 e–
C 4A 1 × 4 e– = 4 e–
H 1A 5 × 1 e– = 5 e–
Total: 14 valence e–
The skeletal structure H3CNH2 gives us a clue on how the molecule is connected.
