How to deduce the bond angle in h2o2?
1. Can you draw a Lewis structure of the molecule?
2. Have you studied the VSEPR Theory?

Think about the electron pairs involved in the central atoms, oxygen in this case. If you follow the VSEPR rule, where electron pairs repel each other as far apart as possible and lone pairs even further. I suggest learning the sort of shapes associated with different numbers of bond pairs and lone pairs. In this case, the arrangement around oxygen is the same as in water ( 2 bond pairs and 2 lone pairs) which gives a non-linear geometry with an angle of 104.5 degrees.
