WebAnswer: Atoms react to obtain an electron configuration which is the least energy and stable. For elements less than Atomic no. 20, They react to get 8 electrons in the valence shell. But this is not a hard rule, other configurations and exceptions are possible. There are many other factors that ... WebPolarizabiity Electron withdrawing groups Rule #4 Stabilizing positive charge If the resonance form has a positive charge, try and find a resonance form in which all octets are full (Rule #2) If all octets are not full, place positive charge on the atom best able to support a carbocation (i.e. the most substituted carbon) Rule #5 - Aromaticity ...
Octet Rule – Examples and Exceptions - Vedantu
WebOct 23, 2015 · Re: Why does Sulfur accommodate expanded octet? Sulfur may be in the same group as Oxygen, but it is in a period below Oxygen. This extra period correlates to an extra energy level. Sulfur is in the 3rd period, meaning it has a highest energy level of n=3. This means Sulfur has access to the 3s, 3p, and 3d orbitals. WebJul 31, 2014 · For n=2 (C, N, O, F) the octet rule is iron-clad. The third and later period non-metals can break the rule. For example, the sulfate anion can be drawn as a tetrahedral of singly-bonded oxygens, but the more correct way to draw it is two double-bond oxygens and two single-bond oxygens. Similarly for sulfur hexafluoride (SF_6). Sulfur has ... aliverti en vivo
Octet Rule Brilliant Math & Science Wiki
WebDec 3, 2024 · In the above structure, you can see that the central atom (chlorine) forms an octet. The outside atoms (oxygens) also form an octet, and hydrogen forms a duet. Hence, the octet rule and duet rule are satisfied. Also, the above structure is more stable than the previous structures. Therefore, this structure is the stable lewis structure of HClO 2. WebThis chemistry video tutorial discusses the exceptions to the octet rule while providing the lewis dot diagrams of the molecular compounds involved. BH3 has...
