Question

which of the following has maximum bond angle? options- 1)Nh3. 2)Co2. 3)Ch4.
Its urgent..

Answer 1

Bond angles are the geometrical parameters which determine the angle of each atom. 

The bond angle of NH3 is 107 degrees. 

The bond angle of CO2 is 180 degrees. 

The bond angle of CH4 is 109.5 degree. 

Hence comparatively CO2 has the maximum bond angle among these three substances.
