GeH₄ - Germanium Tetrahydride (Germane):

First draw the Lewis dot structure:

Electron geometry: tetrahedral. Hybridization: sp³

Then draw the 3D molecular structure using VSEPR rules:
  Click and drag the molecule to rotate it.

Decision:
The molecular geometry of GeH₄ is tetrahedral with a symmetric charge distribution.
Therefore this molecule is nonpolar.
