The Lewis structure of
Concept Introduction:
A covalent bond is a bond that is formed from the mutual sharing of electrons between atoms. Lewis structures are representations of the covalent bond. In this, Lewis symbols show how the valence electrons are present in the molecule.
Steps to write Lewis structures are as follows:
1. The skeleton structure with single bonds between all bonded atoms has to be written
2. Sum the valence electrons of the atoms in the molecule.
(a) For cations, one electron is subtracted for each positive charge.
(b) For anions, one electron is added for each negative charge.
3. Subtract two electrons from total number of valence electrons for each bond in the skeleton structure.
4. Count the number of electrons required to satisfy the octet rule for each atom in the structure. If the number of electrons needed is less than the number remaining, add one bond for every two electrons needed between atoms to attain an octet.
5. The remaining electrons are placed as lone pairs on atoms that need them to satisfy the octet rule.
In octet rule, the central has eight electrons around it. The molecules that have more than eight electrons around it does not obey the octet rule.

Chemistry: Principles and Practice
- NH2 1. CH3–MgCl 2. H3O+ ? As the lead product manager at OrganometALEKS Industries, you are trying to decide if the following reaction will make a molecule with a new C - C bond as its major product: If this reaction will work, draw the major organic product or products you would expect in the drawing area below. If there's more than one major product, you can draw them in any arrangement you like. Be sure you use wedge and dash bonds if necessary, for example to distinguish between major products with different stereochemistry. If the major products of this reaction won't have a new C - C bond, just check the box under the drawing area and leave it blank. Click and drag to start drawing a structure. This reaction will not make a product with a new C - C bond. Х ☐: Carrow_forwardPredict the major products of this organic reaction. If there will be no major products, check the box under the drawing area instead. No reaction. : + Х è OH K Cr O 2 27 2 4' 2 Click and drag to start drawing a structure.arrow_forwardLaminar compounds are characterized by havinga) a high value of the internal surface of the solid.b) a high adsorption potential.arrow_forward
