Does So3 obey octet rule?

So3 doesn’t follow octet rule, because it forms three double bonds with oxygen atoms, and thus,has 6+ 6(obtained from oxygen atoms)=12 electrons.

Does co2 obey the octet rule?

In carbon dioxide each oxygen shares four electrons with the central carbon, two (shown in red) from the oxygen itself and two (shown in black) from the carbon. All four of these electrons are counted in both the carbon octet and the oxygen octet, so that both atoms are considered to obey the octet rule.

Why is sulfur dioxide an exception to the octet rule?

Here the sulfur atom has six electron pairs in its valence shell. An atom like phosphorus or sulfur which has more than an octet is said to have expanded its valence shell. This can only occur when the valence shell has enough orbitals to accommodate the extra electrons.

Does ClF3 obey octet rule?

There are ten electrons three bond pairs and two lone pairs about the central chlorine atom so ClF3 does not obey octet rule.

Does cl2 obey octet rule?

Chlorine has seven valence electrons, so if it takes one it will have eight (an octet). Chlorine has the electron configuration of argon when it gains an electron. The octet rule could have been satisfied if chlorine gave up all seven of its valence electrons and sodium took them.

Which elements must follow octet rule?

The octet rule is only applicable to the main group elements. The molecules of the halogens, oxygen, nitrogen, and carbon are known to obey the octet rule. In general, the elements that obey this rule include the s-block elements and the p-block elements (except hydrogen, helium, and lithium).

Does SF2 obey the octet rule?

SF2, SF4, SF6, SO2. The compounds in which S do not obey octet rule are SF4, SF6 and SO2​. Sulphur atom has six electrons in the valence shell. It forms six single covalent bonds with six flourine atoms utilising all the valency electrons and thereby attains 12 electrons in the outer shell.

Does clf3 have an expanded octet?

The ‘octet’ rule is based upon available ns and np orbitals for valence electrons (2 electrons in the s orbitals, and 6 in the p orbitals). Beginning with the n=3 principle quantum number, the d orbitals become available (l=2).
