Are oxoacids of phosphorus and sulfur covered?+
Yes. Structures and basicities of H3PO2, H3PO3, H3PO4 and H2SO3, H2S2O7, oleum are drawn out — including the P–H/S–H bond counts that determine basicity.
Do the notes include diborane structure?+
Yes — the banana-bond structure of B2H6 with 3-centre 2-electron bonds is drawn, along with its preparation and reactions (hydroboration, hydrolysis).
Are interhalogen compounds discussed?+
Yes. AB, AB3, AB5, AB7-type interhalogens are covered with hybridisation, geometry (using VSEPR), and the reactivity trends across the series.
