Why is the molecule SF4 an exception to the octet rule?

Anonymous

Updated: 2/21/2023

The molecule SF4 doesn't have eight electrons like most atoms, it can expand the octet because sulfur has 6 valence electrons and each fluorine only needs one electron to share with sulfur so that leaves to remainder.

Related Questions

Which doesn't violate the octet rule sf4 krf2 cf4 xef4 icl4-?

CF4 and XeF4 do not violate the octet rule. In CF4, carbon forms four covalent bonds with fluorine, fulfilling the octet rule. In XeF4, xenon forms four covalent bonds with fluorine and has two lone pairs, also satisfying the octet rule.

Is SF4 a resonance structure?

SF4 is not a resonance structure; it is a molecular compound that consists of one sulfur atom covalently bonded to four fluorine atoms. Resonance structures involve the shifting of electrons within a molecule to generate different possible structures, but SF4 does not exhibit this property.

Why SF4 is Seesaw shaped?

SF4 has a seesaw shape due to the presence of four substituents around the sulfur atom, causing the molecule to take on a trigonal bipyramidal geometry. The shape can be explained by considering the repulsion between the lone pair of electrons on sulfur and the bonding pairs, resulting in the bending of the molecule to minimize repulsion and achieve stability.

What is the molecular shape of SF4?

The shape of SF4 is Sea Saw

WHAT IS THE CHEMICAL FORMULA OF sulfur tetrafluoride?

The chemical formula of sulfur tetrafluoride is SF4.

How many sets of lone pairs are around sulfur in SF4?

There is one set of lone pairs around sulfur in SF4.

Is SF4 covalent?

CF4 is a covalent bond, because both elements are "nonmetals"

Is SF4 an molecular compound?

0.632 D

What is the Oxidation number for SF4?

The oxidation number for sulfur in SF4 is +4. This is because fluorine typically has an oxidation number of -1 and there are four fluorine atoms in SF4, resulting in a total charge of -4. Therefore, the sulfur must have a charge of +4 to balance the molecule.

How VSEPR theory help explain SF4 shape?

VSEPR theory predicts the molecular geometry of a molecule by considering the repulsion between electron pairs around the central atom. In the case of SF4, there are five regions of electron density around the sulfur atom, leading to a trigonal bipyramidal geometry. However, one of the regions is a lone pair, causing greater repulsion and pushing the fluorine atoms closer together, resulting in a see-saw shape for SF4.

What is the systematic name for SF4?

The systematic name for SF4 is sulfur tetrafluoride.

What is the boiling point of SF4?

The boiling point of SF4, or sulfur tetrafluoride, is -38.5 degrees Celsius or -37.3 degrees Fahrenheit.
