If we take a look on the following compounds in the Oxygen family, the bond angle increases as we go down the group as : H2O > H2S > H2Se Whats the reason for this increase? Is that : 1. Oxygen is more electronegative than the two, so it holds its lone pairs more tightly than the other two..Thus, the lone pairs are tightly bound to the oxygen atom, not free to wander about & repel the bond pair with hydrogen, therefore making the angle much larger. OR 2. Oxygen being more electronegative, pulls the two bond pairs close to itself, as the bond pairs move closer, the distance btw them decreases & this makes the bond angle larger. Which of the above reason is right? Thanks!
