P Block Elements

The incorrect statement is:D. is a tribasic acid.This assertion is incorrect because (hypophosphorous acid) is actually a monobasic acid. It can only donate one proton ( ) per molecule in an aqueous solution. Here are the correct classifications for these acids: (phosphoric acid) is a tribasic acid. (phosphorous acid) is a dibasic acid. (hypophosphorous acid) is a monobasic acid.

Fullerenes are spherical carbon molecules with a cage-like structure, composed entirely of carbon atoms arranged in hexagonal and pentagonal rings.

The smallest P-P-P bond angle in the highly reactive allotrope of phosphorus, which is white phosphorus , can be determined by looking at the structure of the molecule.In white phosphorus, the molecule consists of four phosphorus atoms arranged in a tetrahedral shape, forming a tetrahedron. Each phosphorus atom is bonded to three other phosphorus atoms, creating a strained ring structure. The bond angles in a tetrahedron are as all sides are equilateral triangles.Therefore, the smallest P-P-P bond angle in the highly reactive allotrope of phosphorus (white phosphorus) is .
