The correct order of bond angles (smallest first)
The correct order of bond angles (smallest first) in H2S, NH3, BF3 and SiH4 is
- H2S < NH3 < SiH4 < BF3
- NH3 < H2S < SiH4 < BF3
- H2S < SiH4 < NH3 < BF3
- H2S < NH3 < BF3 < SiH4
Answer
The correct order of bond angle (smallest first) is
H2S < NH3 < SiH4 < BF3
92.6° < 107° < 109° < 120°
The correct option is C.
