Respuesta :
1. Two bonding domains and two nonbonding domains (or lone pairs): Bent shape and bond angle is 104.5 degree.
2. For bonding domains and zero nonbonding domains: Tetrahedral shape and bond angle is 109.5 degree.
3. Two bonding domains and zero nonbonding domains: Linear shape and bond angle is 107 degree.
4. Two bonding domains and one nonbonding domain: Bent shape and bond angle is 120 degree.
5. Three bonding domains and zero nonbonding domains: Trigonal planar shape and bond angle is 120 degree.
6. Three bonding domains and one nonbonding domain: Trigonal pyramidal shape and bond angle is 107 degree.
From this, it is clear that two bonding domains and two nonbonding domains will be having the smallest bond angle.
Answer:
two bonding domains (or bonding pairs) and two nonbonding domains (or lone pairs)
