Multiple choice

Which of the following matches is incorrect?

  1. Order of stability: O2+>O2 >O2-

  2. Order of bond angles: H2S>>NH3>BF3>SiH4

  3. Order of dipole moment: NH3>PH3>AsH3>SbH3

  5. All are correct
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

H2S (Bent with bond angle 98o) NH3 (pyramidal with bond angle 105o) SiH4 (Tetrahedral with bon d angle 109.5o) BF3  (Trigonal planar with bond angle 120o) Correct order is BF3>SiH4>NH3> H2S
