Which of the following describes a scenario in which the molecular geometry would have the smallest bond angle(s)?
four bonding domains (or bonding pairs) and zero nonbonding domains (or lone pairs)
two bonding domains (or bonding pairs) and two nonbonding domains (or lone pairs)
three bonding domains (or bonding pairs) and one nonbonding domain (or lone pair)
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)
#Bonding pairs=BP, # Lone pair = LP
1) 4-BP and 0-LP = Tetrahedral shape and bond angle =109.5'
2) 2-BP and 2- LP = Bent shape and bond angle = 104.5'
3) 3-BP and 1-LP = Trigonal Pyramidal shape and bond angle =107'
4)2-BP and 0-LP = Linear shape and bond angle =180'
5) 2-BP and 1-LP = Bent shape and bond angle =120'
6)3-BP and -LP = Trigonal planar shape and bond angle =120'
From this clearly can see that 2-BP and 2- LP will be having smallest bond angle.
