Question

Decide whether each molecule or polyatomic ion is polar or nonpolar. If the molecule or polyatomic ion is polar, write the chemical symbol of the atom closest to the negative side. For example, if the molecule were and you decided the hydrogen atom was closest to the negative side of the molecule, you'd enter H at the latest coulumn.
Molecules Polarity atom closest to negative site

H3O

CN

SiF4

Answer 1

Answer:

See explanation

Explanation:

H3O is polar and H is closest to the negative side of the molecule

CN is polar and C is closest to the negative side of the molecule

SiF4 is nonpolar

Note SiF4 is nonpolar because of its symmetrical nature. The unequal pull of the lone pair in H3O makes it polar.

CN is polar because of unequal charge distribution.
