We’re being asked to draw the Lewis structure for hydrazine (NH2NH2). We first need to determine the total number of valence electrons present in the molecule:
Group Valence Electrons
N 5A 2 × 5 e– = 10 e–
H 1A 4 × 1 e– = 4 e–
Total: 14 valence e–
Hydrazine (NH2 NH2 ), hydrogen peroxide (HOOH), and water (H2 O) all have exceptionally high surface tensions in comparison with other substances of comparable molecular weights.
Draw the Lewis structure for hydrazine (NH2 NH2).
