Which of the following compound has the smallest bond angle (X — A — X) in each series respectively? — Chemical Bonding Chemistry Question

💡 Solution & Explanation

[SEE DIAGRAM] Order of decreasing bond angle: OSF2 < OSCl2 < OSBr2 (on the basis of electronegativity of halogens); SbI3 < SbBr3 < SbCl3 (on the basis of electronegativity of halogens); PI3 > AsI3 > SbI3 (involvement of s-orbital in hybridisation decreases downward in a group).
