Q:

Is SeF6 polar or nonpolar?

A:

Quick Answer

SeF6 is not polar. Although the Se-F bond is polar, the SeF6 molecule has an octahedral coordination symmetry, and the net dipole moment due to the six polar Se-F bonds is zero.

Full Answer

A polar molecule has a net dipole moment. In order to determine whether a molecule is polar, the valence shell electron pair repulsion rules should first be used to identify the three-dimensional geometry of the molecule. Then, the net dipole moment due to the polar bonds in the molecule should be determined. These bonds often have atoms of different electronegativities on their two ends. For example, selenium has an electronegativity of about 2.55, while fluorine has an electronegativity of about 3.98.

    Is SF6 polar?

    A:

    SF6 is not polar. Although the S-F bond is polar, the SF6 molecule has octahedral symmetry, and the effects of the dipoles of the six bonds cancel one another out.

    Is XeF4 polar?

    A:

    Xenon Tetraflouride, or XeF4, is a not a polar molecule. XeF4's geometric structure and symmetry causes the intramolecular forces within the molecule to cancel out, making XeF4 a non-polar molecule.

    Is NCl3 polar?

    A:

    NCl3 is a slightly polar molecule. This is because nitrogen has a lone pair of electrons that repels the bonded electron pairs of the N-Cl covalent bonds, thus giving the molecule an asymmetric structure where the polarities of the bonds do not cancel each other out.

    Is HCl polar?

    A:

    Hydrogen chloride is a polar molecule because it contains a polar, covalent bond between hydrogen and chlorine. This gives the hydrogen a partial positive charge and the chlorine a partial negative charge.
