Which of the following describes a scenario in which the molecular geometry would have the smallest bond angle(s)? View Available Hint(s) Which of the following describes a scenario in which the molecular geometry would have the smallest bond angle(s)? two bonding domains (or bonding pairs) and two nonbonding domains (or lone pairs) four bonding domains (or bonding pairs) and zero nonbonding domains (or lone pairs) two bonding domains (or bonding pairs) and zero nonbonding domains (or lone pairs) two bonding domains (or bonding pairs) and one nonbonding domain (or lone pair) three bonding domains (bonding pairs) and zero nonbonding domains (or lone pairs) three bonding domains (or bonding pairs) and one nonbonding domain (or lone pair)

Answer 1

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.
