Explanation: XeO3or Xenon trioxide is isostructural with BrO3 - .
Both have a pyramidal orbital configuration. There is one Xe atom at the apex. It also has a lone pair and three oxygen atoms at the corners of a trigonal base. Bond angle is 109. 5
Explanation: H3PO3 or orthophosphorous acid is a dibasic oxoacid of phosphorous. As we can see it has two P - OH bonds. Which makes it dibasic. The number of P - OH bonds can give the basicity of the acid. The phosphorous is tetrahedrally surrounded by the H and O atoms
