The Lewis diagram for PO(OH)3 is: The electron-pair geometry around the P atom in PO(OH)3 is There arelone pair(s) around the central atom, so the geometry of PO(OH)3 is B. The Lewis diagram for SeH2 is: The electron-pair geometry around the Se atom in SeH2 is There are lone pair(s) around the central atom, so the geometry of Sel2 is
