Prediction of molecular geometry - 1 | Molecular Geometry

What is the electron-domain geometry and the molecular shape of the following molecules:

H2O, SiO2, AlCl3 and PCl5 ?

Electron-domain Geometry = EDG; Molecular Shape = MS
 

H2O ⇒ AX2E2 ⇒ EDG = tetrahedral, MS = bent

SiO2 ⇒ AX2 ⇒ EDG = linear, MS = linear

AlCl3 ⇒ AX3 ⇒ EDG = trigonal planar, MS = trigonal planar

PCl5 ⇒ AX5 ⇒ EDG = trigonal bipyramidal, MS = trigonal bipyramidal
