Question
Out of \[\ce{H2O}\] and \[\ce{H2S}\], which one has higher bond angle and why?
Solution
Oxygen is more electronegative than sulphur, the bond angle of \[\ce{H2O}\] is greater, and the body pair electron of an \[\ce{OH}\] bond will be closer to oxygen, causing bond-pair bond-pair repulsion between bond pairs of two \[\ce{OH}\] bonds.
