The compound that has the largest H – M – H bond angle ( M   =   N ,   O ,  …

The compound that has the largest H–M–H bond angle (M = N, O, S, C), is :
  1. H2O
  2. NH3
  3. H2S
  4. CH4

Solution

Comparison of H2O and NH3

H2O :

sp3,ℓ·p=2, B. A.=104°30°
H2S→ No hybridisation [Drago's rule], bond angle =92°


NH3 : sp3  hybridisation ,ℓ.p=1,B.A.=107°
