Question

arrange water ammonia and methane in decreasing order od their bond angle
​

Answer 1

Answer:

NH3 is better known as ammonia to us, CO2 as carbon di-oxide, H2O as water and CH4 as methane.

The bond angle according to the theory of VSEPR is the angle between the two electron bonds.

The number of lone pairs of electron in H2O is 2, where as it is one in NH3 and none in CH4.

Explanation:

Answer 2

Answer:

Here, methane would have the largest bond angle of 109 degree then ammonia would have bond angle of 10 7.5 degree and then water will have bond angle of 104 degree this is because of the increasing number of lone pairs on the central atom that it The lone pair and bond pair repulsion is increases and thus the bond angle decreases
