Explain the following types of structures.
1) Lewis structure
2) Dash structure
3) condensed structure
4) bond line structure
Answers
Dash structure = A method of representing the three-dimensional structure of a molecule in which solid lines represent bonds in the plane of the image, wedges represent bonds towards the viewer and dashed lines represent bonds away from the viewer.
Condensed Structure=
A molecular formula tells only the numbers of atoms of each element in a molecule of the compound. A condensed structure shows all atoms, but it omits the vertical bonds and most or all of the horizontal single bonds.
Bond line structure = The bond-line structure is a simplified and common drawing style for organic compounds. In this style, all carbon atoms and most hydrogen atoms are implied and not drawn explicitly.

Answer Number 1
Lewis Structure : A Lewis Structure is a very simplified representation of the valence shell electrons in a molecule. It is used to show how the electrons are arranged around individual atoms in a molecule. Electrons are shown as "dots" or for bonding electrons as a line between the two atoms.

Answer Number 2
Dash Structure: The wedge and dash notation is used to represent three-dimensional structures of molecules using a two-dimensional surface, like a sheet of paper or a computer screen. It is commonly used in organic chemistry, though you may see it any time a molecule structure is given.

Condensed Structure:A condensed structure shows all atoms, but it omits the vertical bonds and most or all of the horizontal single bonds.

Answer Number 4
Bond Line Structure: Bond-line structure (bond-line formula, skeletal structure, skeletal formula): A representation of molecular structure in which covalent bonds are represented with one line for each level of bond order.
