When Ge binds to the two Cl, 2 single (sigma) bonds are created, resulting in a Lewis structure with:
.. .. ..
:Cl-Ge-Cl:
.. ..
Since the Ge is surrounded by three things (two atoms and a lone pair), a trigonal planar shape is expected. This creates sp2 hybridization. sp2 hybridization results in trigonal planar shapes, but because a lone pair takes up more space than bound atoms, the shape is bent or irregular. Though I don't know the exact nomenclature for this shape, I would call it bent or irregular trigonal planar (atom bond angles < 120 degrees).
The molecular shape name for C3H8 is a tetrahedron.
Parent Shape: Trigonal bipyrimidal Actual shape: Trigonal Planar
The molecular shape of a magnesium hydride molecule is linear. Magnesium has a +2 charge, while hydride has a -1 charge, resulting in a linear molecular shape.
Trigonal pyramidal
The bond angle in silicon disulfide (SiS2) is approximately 105 degrees, and the molecular shape is bent/angular.
TeCl2 is expected to have the highest boiling point among OCl, SCl2, SeCl2, and TeCl2 because it has the largest atomic size and highest molar mass. As molecular size and molar mass increase, the van der Waals forces between molecules also increase, resulting in higher boiling points.
The compound name for TeCl2 is tellurium dichloride.
The molecular shape of SCl6 is octahedral.

The molecular shape name for C3H8 is a tetrahedron.
Parent Shape: Trigonal bipyrimidal Actual shape: Trigonal Planar
V-shape
A compound that does not have a bent molecular shape is carbon dioxide (CO2). It has a linear molecular shape due to the arrangement of the three atoms in a straight line.
The molecular shape of CIF2 is linear. This is because there are only two atoms bonded with the central atom, which results in a linear molecular geometry.
The molecular shape of a magnesium hydride molecule is linear. Magnesium has a +2 charge, while hydride has a -1 charge, resulting in a linear molecular shape.
