Why can sulfur have an expanded octet but not oxygen?

WebExpansion of octet is endothermic and thus energy unfavorable. The atomic size of F is very small. This makes the bond length of Se−F bond short enough to release sufficient energy in bond formation to compensate the energy needed in expansion of octet. This makes the expansion of octet feasible. Continue Reading 2 Sponsored by Forbes Advisor WebExpanded octet occurs when an atom is able to have more than 8 valence electrons. For example, in SO₃, the sulfur atom forms 6 covalent bonds, hence it has 12 valence electrons. Expansion of octet is possible only from Period 3 elements onwards, due to the presence of low-lying empty d orbitals that can accommodate the extra electrons. brian rowlson

"WebThe octet rule has exceptions because not all atoms have 8 electrons surrounding them. Major categories of exceptions: 1) Odd octets, seen in electron species, molecules, or ions with an odd number of valence electrons (NO). 2) Incomplete octets, seen in molecules or ions with fewer than 8 electrons surrounding an atom (BFsub3).

Does SiF4 obey the octet rule? - Answers

WebGenerally not more than sixteen electrons per atom participate in covalent bonding. Finally, note that an expanded valence shell is also called an expanded octet. The most important note is to understand when an element can use an expanded octet based on its availability of electrons beyond the eight valence electrons. WebExpansion of octet is endothermic and thus energy unfavorable. The atomic size of F is very small. This makes the bond length of Se−F bond short enough to release sufficient energy in bond formation to compensate the energy needed in expansion of octet. This makes the expansion of octet feasible.

WebNov 2, 2024 · Re: Extended Octet for Sulfur. Sulfur can have an expanded octet because it is in Row 3 of the periodic table, meaning that the quantum number n is equal to 3. When n=3, l can be 0, 1, or 2 according to the rules for quantum numbers. This means that elements in Row 3 have the S, P, and D subshells available to them to hold electrons. WebThe Octet Rule is called a rule instead of a law as it is often broken. In fact it has limited application to outside organic molecules. NO is an inorganic gas, with an odd number of electrons in the combined valencies of N (with 5 e-) and O (with 6 e-) for a total of 11 e- to be assigned in the Lewis Dot Structure.

WebOct 8, 2024 · Expansion of Valence Shell The typical structural formula for ATP (adenosine triphosphate) shows three single bonds and one double bond on the phosphorus atom, for a total of 5 electron pairs. This is possible because P has 3d orbitals as well as 3s and 3p orbitals to accommodate the electrons. WebThe 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 …

WebThe existence of hypervalent compounds would appear to deal a severe blow to the validity of the octet rule and Lewis' approach to covalent bonding if the expansion of the octet could not be rationalized or its occurrence predicted. Fortunately, it can be rationalized, and the occurrence of hypervalence can be anticipated. WebExpansion; Ensembles de fonctionnalités; À propos de nous.
