How to draw organic molecules?
The different ways to draw organic molecules include Kekulé (straight-line), Condensed Formulas, and Bond-Line Formulas (zig-zag). It will be more helpful if you become comfortable going from one style of drawing to another, and look at drawings and understanding what they mean, than knowing which kind of drawing is named what.
What is an example of a drawing that incorporates all three ways to draw organic molecules?
An example of a drawing that incorporates all three ways to draw organic molecules would be the following additional drawing of Retin ol. The majority of the drawing is Bond-line (zig-zag) formula, but the -CH 3 are written as condensed formulas, and the -OH group is written in Kekul é form.
Why do molecules end up looking like zig zag lines?
This formula is full of bonds and lines, and because of the typical (more stable) bonds that atoms tend to make in molecules, they often end up looking like zig-zag lines. If you work with a molecular model kit you will find it difficult to make stick straight molecules (unless they contain sp triple bonds) whereas zig-zag molecules and bonds are much more feasible.
What are the lines in a 4-carbon chain?
Above are 4-carbon chains with attached OH groups or Cl and Br atoms. Remember that each line represents a bond and that the carbons and hydrogens have been omitted. When you look at or draw these structures, the straight lines illustrate atoms and bonds that are in the same plane, the plane of the paper (in this case, computer screen). Dashed lines show atoms and bonds that go into the page, behind the plane, away from you. In the above example, the OH group is going into the plane, while at the same time a hydrogen comes out (wedged).
How to show 3D structure of a molecule?
A widely used way of showing the 3D structure of molecules is the use of dashes, wedges, and straight lines. This drawing method is essential because the placement of different atoms could yield different molecules even if the molecular formulas were exactly the same. Below are two drawings of a 4-carbon molecule with two chlorines and two bromines attached.
How to compare two molecules?
An easier way to compare the two molecules is to rotate one of the bonds (here , it is the bond on the right): Notice how the molecule on the right has both bromines on the same side and chlorines on the same side, whereas the first molecule is different.
Which atoms want to have a closed shell?
All atoms want to have their valence shell full, a "closed shell.". Hydrogen wants to have 2 e - whereas carbon, oxygen, and nitrogen want to have 8 e -. When looking at the different representations of molecules, keep in mind the Octet Rule.
What are organic molecules?
But what is an organic molecule? Organic molecules are usually composed of carbon atoms with other atoms attached, such as hydrogen, oxygen , and nitrogen.

What are the four types of organic compounds?
There are four main types, or classes, of organic compounds found in all living things: carbohydrates, lipids, proteins, and nucleic acids . In addition, there are other organic compounds that may be found in or produced by some organisms. All organic compounds contain carbon, usually bonded to hydrogen (other elements may be present as well).
How are carbohydrates classified?
Carbohydrates are classified according to how many subunits they contain. Simple carbohydrates are called sugars. A sugar made of one unit is a monosaccharide. If two units are joined together, a disaccharide is formed. More complex structures form when these smaller units link to each other to form polymers. Examples of these larger carbohydrate compounds include starch and chitin.

What is organic chemistry?
Organic chemistry was once thought to be confined to the study of substances produced as part of the natural processes of living organisms, but as Friedrich Wohler discovered in the early 1800s, organic compounds can be synthesized from minerals and other non-organic materials in the laboratory. Indeed, modern chemistry and materials sciences have concentrated on the remarkable properties of carbon atoms for the production of synthetic chemicals, pesticides and a host of other things. Organic compounds contain carbon, almost always bonded to another carbon and/or hydrogen.
What is an Organic Compound?
Organic compounds also contain carbon, along with other elements essential for the reproduction of living organisms. Carbon is the main factor as it has four electrons that can accommodate eight electrons in an outer shell. As a result, several forms of bonds can be formed with other carbon atoms and elements such as hydrogen, oxygen, and nitrogen. Hydrocarbons and proteins are strong examples of organic molecules capable of producing long chains and complex structures.
What is a homologous series?

The members of the homologous series can be represented by a general formula and ...
Why are organic compounds important?
Organic compounds are essential because they contain carbon in all living organisms. They are the basic components that move the world in many of the cycles. For example, the carbon cycle which involves exchanging carbon in photosynthesis and cell respiration between plants and animals.
What is the name of the compound that contains carbon?
The compounds in solid, liquid or gaseous state which contain carbon in its molecule are known as organic compounds . There are a large number of organic compounds and therefore a proper systematic classification was required. Organic compounds can be broadly classified as acyclic (open chain) or cyclic (closed chain).

How do sugars bond?
When organic molecules are bound, a bonding site is freed at every member. This occurs by clipping a single hydrogen from one participant and a hydroxide (oxygen-hydrogen) off the other.
What is the structure of proteins?
Proteins are long chains of components known as amino acids consisting of layered structures. The first level is known as the primary structure which is the order of amino acids in every chain. The secondary structure, amino acids is a region that connects to each other and makes local forms like pleated coil sheets. At tertiary structure, the complete molecule is pulled into a 3-dimensional shape mainly through bonds but sometimes via covalent bonds.
