Consider AB2 molecule Calculate % s-character in A—B bond:Corre...
From Bent’s Rule equation, cosx = s/s-1
where x is an bond angle and s is the % s character in the bond, it is clear that if we increase bond angle, the %s Character will be maximum.
Here angle is 150,
⇒ Cosx = s/(s-1)
⇒ Cos 150° = s/(s-1)
⇒ -0.86 = s/(s-1)
⇒ -0.86s +0.86 = s
⇒ 0.86 = 1.86s
⇒ s = 0.86/1.86
⇒ s = 0.462
⇒ %s = 0.462 X 10
⇒ %s = 46.2%

Consider AB2 molecule Calculate % s-character in A—B bond:Corre...
From the relation between bond angle and %s character it is known that with decreasing order of bond angle %s character decreases .
Here the bond angle is 150 degree .
For exactly sp hybridization 180 degree bond angle is required.But here (most probably) due to the repulsion between lone pair of A and A-B bonds ,i.e. lone pair-- bond pair repulsion , the bond becomes more bent resulting the bond angle of 150 degree.
For exactly sp hybridization %s character is 50.
As here the bond angle decreases so %s character will also decrease accordingly , resulting the %s character of 46-47 regarding the statement.
