Complete the paragraph to describe the characteristics of silicon tetrachloride molecule (sih4). the lewis structure and the table of electronegativities are given. the bond polarities of sih4 are the molecular shape is and the molecule is blank options 1: polar, nonpolar blank options 2: trigonal pyramidal, trigonal planar, tetrahedral, linear, bentblank options 3: polar, nonpolar

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

As seen on the diagram, there are four Si-H bonds in a molecule of SiH₄. Electronegativity values:

The two atoms differ in electronegativity. As a result, the Si-H bond is polar.

There are four valence electrons in one Si atom. Each of the four electron will go to a Si-H bond. The Si atom in SiH₄ will have no lone pairs. The four Si-H bonds count towards four electron domains. As a result, the SiH₄ atom is tetrahedral.

Dipoles from each Si-H bond are equal. They are poised in a tetrahedral shape. As a result, their dipole balance each other. Overall, SiH₄ molecule will have no net dipole.

im not exactly sure but i think its b!
