Lewis structure and electron geometry of
Concept Introduction:
Lewis model represents the molecules by the electron dot model which is based on the octet rule.
While writing the Lewis structure of a covalent molecule these steps are followed:
First correct skeleton is written for the molecule
Total number of valence electrons are calculated
Distribution of total number of valence electrons in such a way that it completes the octet configuration of all the constituent atoms.
If any atom lacks the octet configuration the double or triple bonds are added.
Valence shell electron pair repulsion (VSEPR) theory and Lewis model helps in determining the shape of the molecule.
The molecular geometry of a molecule can be determined by consider the total number of electron groups, the number of bonding groups and the number of lone pairs.

- Nitrosyl azide, N4O, is a pale yellow solid first synthesized in 1993. Write the Lewis structure for nitrosyl azide.arrow_forwardBest Lewis Formula and Molecular Geometry A student writes the Lewis electron-dot formula for the carbonate anion, CO32, as a Does this Lewis formula obey the octet rule? Explain. What are the formal charges on the atoms? Try describing the bonding for this formula in valence bond terms. Do you have any difficulty doing this? b Does this Lewis formula give a reasonable description of the electron structure, or is there a better one? If there is a better Lewis formula, write it down and explain why it is better. c The same student writes the following resonance description for CO2: Is there something wrong with this description? (What would you predict as the geometries of these formulas?) d Is one or the other formula a better description? Could a value for the dipole moment help you decide? e Can you write a Lewis formula that gives an even better description of CO2? Explain your answer.arrow_forwardA variety of chlorine oxide fluorides and related cations and anions are known. They tend to be powerful oxidizing and fluorinating agents. FClO3 is the most stable of this group of compounds and has been studied as an oxidizing component in rocket propellants. Draw a Lewis structure for F3ClO, F2ClO2+, and F3ClO2. What is the molecular structure for each species, and what is the expected hybridization of the central chlorine atom in each compound or ion?arrow_forward
