The compound that has the largest H – M – H bond angle ( M = N , O , S , C ) , is :

Options

  1. AH 2 O
  2. BNH 3
  3. CH 2 S
  4. DCH 4

Correct answer

D. CH 4

Step-by-step solution

Comparison   of   H 2 O   and   NH 3 H 2 O   : sp 3 , ℓ · p = 2 , B. A . = 104 ° 30 ° H 2 S → No hybridisation [Drago's rule], bond angle = 92 ° NH 3   :   sp 3     hybridisation   , ℓ . p = 1 , B . A . = 107 °
