Draw electron cross and electron dot structures for the following molecules:
(a) CS, an organic solvent that dissolves sulphur, phosphorus etc
Answers
Answer: Electron dot structures or Lewis dot formulas can be drawn if the molecular formula of the compound is known.
Explanation:
It defines the nature of the bond and the position of the atoms of the molecule that are connected in the molecule.
The representation of molecules in the Lewis electron dot structure, or just the Lewis structure, is in honor of the American chemist Gilbert Newton Lewis.
Lewis dot structures also called electron dot structures are diagrams that describe the chemical bonding between atoms in a molecule. They also show the total number of lone pairs present in each of the atoms that make up the molecule. Lewis defined a base as an electron pair donor and an acid as an electron pair acceptor.
A water molecule consists of one molecule of oxygen and two molecules of hydrogen.
Oxygen has "two bonds" and "two lone pairs" and a complete octet.
Hydrogen gains an octet in its valence shell by sharing a bond with oxygen.
A water molecule generally has the structure H-O-H, and oxygen has six and hydrogen two valence electrons.
For it to be an octet, a total of eight valence electrons should be arranged.
