In the VSEPR model, the geometry of the regions defined by the electron pairs in the valence shell of an atom is called the electron-pair geometry.
A. The Lewis diagram for SCl2 is: C-5-c:
The electron-pair geometry around the Satom in SCl2 is
There are
unshared pair(s) around the central atom, so the geometry of the SCl2 molecule is
H
B. The Lewis diagram for SiH, is:
H-Si-H
H
The electron-pair geometry around the Si atom in SiH, is
There are unshared pair(s) around the central atom, so the geometry of the SiH, molecule is
