SCl4 Molecule

Postby Lelija Kazlauskas 3J » Sun Nov 17, 2019 6:02 pm

Why don't the dipole moments in SCl4 cancel each other out?

Because there is a lone pair that acts as an area of high electron density, thus, affecting the shape of and polarity of the molecule.

There is a lone pair on the S atom, which makes this a polar atom overall. The Cl atoms are not directly opposite from each other, and that's why their dipole moments don't cancel.

When there's a lone pair, it makes the molecular polar because the molecule isn't symmetrical and electrons won't be uniformly distributed.

Molecules with Sulfur as the central atom are often polar because Sulfur can accommodate more than 8 valence electrons. If there is an uneven number of bonded atoms or lone pairs, the molecule will be polar.

Is it safe to assume that a molecule like SCl4 that has a trigonal bipyramidal electron arrangement but with one lone pair, will become a seesaw shape?
