The bond angle in GeH4 is approximately 109. There are 4 steps to solve this one. 1993). The lone electron pairs exerts a little extra repulsion on the three bonding hydrogen atoms to create a slight compression to a 107 o bond angle. If one or two of these doublets are non-bonding, they are more cumbersome than covalent bonds. Calculate the hybridization of the central atom. Final Answer: The hybridization of G e H 4 is s p 3 , the shape is tetrahedral, and the bond angle is approximately 109. 5°, but with the presence of a lone pair of electrons the bond angle is instead 107. The three pairs of bonding electrons lie at an angle of 119 o. 5° because of no lone pair of electrons on an atom. I. SnH4 4.
