According to the given statement option have the lowest boiling point SiH₄.
The correct option is B.
The strength of intermolecular forces, it is important to keep in mind, is a key factor in determining a substance's boiling point.
In the compounds listed in the question, the Si-H connection is the least polar of all the bonds. The reason for this is that a nonpolar covalent bond forms as a result of the very small difference in electronegativity between silicon and hydrogen.
The boiling points of the other compounds are higher than those of SiH₄ because they have more polar bonds, which in turn results in a greater degree of molecular dipole interaction.
With the chemical formula SiH₄, silane is a synthetic substance. It is a toxic, colorless gas that is similar to acetic acid in smell and has a pyrophoric, sharp, and offensive odor. As a forerunner to elemental silicon, silane has practical applications.
