We’re being asked to identify the bonding pairs and lone pairs in water (H2O). We must first draw a Lewis structure for H2O.
Determine the total number of valence electrons present in the molecule:
Group Valence Electrons
H 1A 2 × 1 e– = 2 e–
O 6A 1 × 6 e– = 6 e–
Total: 8 valence e–
Identify the number of bonding pairs and lone pairs of electrons in water
A) 1 bonding pair and 2 lone pairs
B) 2 bonding pairs and 1 lone pair
C) 1 bonding pairs and 1 lone pair
D) 2 bonding pairs and 2 lone pairs
E) 3 bonding pairs and 2 lone pairs
