Question

Options for the first box: polar, nonpolar Options for the second box: trigonal pyramidal, trigonal planar, tetrahedral, linear, bentOptions for the third box: polar and nonpolar

Answer 1

The bond polarities of SiH4 are polar, the molecular shape is tetrahedral, and the molecule is nonpolar.

Step-by-step explanation

The bond polarities of SiH4 are polar, this is because of the strong electronegativities difference in the bond that exists between Silicon and Hydrogen.

The molecular shape is tetrahedral, because of the same symmetric charge distribution around them.

The molecule is nonpolar because the net four S-H bonds dipole moments are zero.
