Chemical Bonding And Molecular Structure Question 241
Question: The correct order of bond angles (smallest first) in $ H_2S,NH_3,BF_3 $ and $ SiH_4 $ is [AIEEE 2004]
Options:
A) $ H_2S<NH_3<SiH_4<BF_3 $
B) $ NH_3<H_2S<SiH_4<BF_3 $
C) $ H_2S<SiH_4<NH_3<BF_3 $
D) $ H_2S<NH_3<BF_3<SiH_4 $
Show Answer
Answer:
Correct Answer: C
Solution:
The correct order of bond angle (Smallest first) is $ H_2S<NH_3<SiH_4<BF_3 $
$ 92.6{}^\circ <107{}^\circ <109{}^\circ 28’<120{}^\circ $
