What is the value of the bond angles in SiH4?

Answer 1

Silicon tetrahydride is a tetrahedral molecule. The silicon atom is directly bonded with four hydrogen atoms where the hydrogen atoms lie at the corners of the tetrahedron. According to the VSEPR theory, it has a bond angle of 109.5 degrees.

Answer 2

Silica, SiO2, is network giant covalent molecule with each Si atom surrounded by 4 oxygen atoms, and each oxygen atom briding between two silicon atoms. The Si-O bonds are single polar covalent, ( the electronegativity difference is 1.54)

Answer 3

Four covalent Si-H bonds are present in SiH4.

Answer 4

The bond angles in SiH4 (silane) are approximately 109.5 degrees, which is consistent with a tetrahedral molecular geometry.

Answer 5

8 valence electons

Answer 6

109.5
