The p-Block Elements: Oxoacid Structures, Shapes and… | StemPy Lab
Standard content
“The p-Block Elements: Oxoacid Structures, Shapes and Reaction Puzzles in Depth” is available to Standard subscribers.
Beyond the textbook. We draw and compare the oxoacids of phosphorus, sulphur and chlorine, and work out the shape of any p-block molecule or ion. We also balance redox and disproportionation reactions and solve the identification puzzles. The level of JEE Advanced, A-Level and IB Higher Level, with a full timed paper.

Oxoacid structures and acid strength: A cola, a car battery and a tub of bleach all depend on oxoacids. We learn to read an oxoacid like a map: where the double bonds, the OH groups, the bridges and the O-O links are. From the map we get the oxidation state, the basicity and the strength.
Shapes of p-block molecules and ions by VSEPR: Every molecule has a shape, and the shape decides its polarity and its reactions. We use one method for every molecule of groups 15 to 18: count the electron pairs on the central atom, place the lone pairs, and read the shape.
Redox, disproportionation and identification puzzles: Many reactions of the p-block are redox reactions, and some are puzzles. We balance them by the ion-electron method, study the reactions where one element is both oxidised and reduced, measure by iodometry, follow the chains of conversions and solve identification puzzles.
