Why are we able to show structures of compounds with different position of electron, but with same position of them? Shouldn't the structure become unstable due to this? Let's take benzene for the example of resonance.We know that in reality benzene has no pure single or double bond. How...

Draw the Lewis structure for NO- with all resonance forms. State its formal charge and polarity. What is its molecular geometry? A) Draw lewis structures for CO2, SO2, AND NO3-. B) Give the electron pair geometry and the molecular geometry of the three sp...
The steps to construct a Lewis structure are the following: 1. Count the total number of valence electrons (including all ligands, and the central atom). 2. Create a skeleton of the molecule by connecting all ligands to the central atom with one bonding electron pair. ...

(i.e., free) and contains one or more unpaired electron. The presence of an unpaired electron is immediately evident from the Lewis dot depiction for NO (Fig. 2). However, the unpaired electron is not associated solely with the nitrogen atom of NO (as indicated by theLewis structure), ...
rule. Then, I saw that the correct structure is the one on the right. Why is the structure on the right favored over the one on the left? They both have the same formal charges. So shouldn't the one that satisfies the octet rule be favored over the one with an extended octet?
Lewis Structure: Lewis's structure gives the arrangement of valence electrons of all the atoms in the molecule. In some molecules, one structure cannot describe the molecule completely, so more than one Lewis structure is possible for such molecules. ...
Draw the Lewis dot structure for (CH_3OH_2)^+. Draw and explain the Lewis dot structure of oxygen. Draw the lewis structure of CO,CO_{3} and CO_{3}^{-2} including resonance structure. Draw the Lewis structure for BrF_3.
