Isomer

 This time I will memebahas about the new isomer morning I learned while studying chemistry. For more details, read the following article.

Isomers
In chemistry, isomers are molecules with the same chemical formula (and often with the same type of bond), but has a different arrangement of atoms (can be likened to an anagram). Most isomers have similar chemical properties to each other. There is also a term of nuclear isomers, namely nuclei that have different levels of excitation.
A simple example of an isomer is C3H8O. There are three isomers with the chemical formula, the two molecules of alcohol and an ether molecule. Two molecules of alcohol is 1-propanol (n-propyl alcohol, I), and 2-propanol (isopropyl alcohol, II). In molecule I, the oxygen atoms attached to the carbon tip, whereas the second molecule of oxygen atoms attached to the carbon second (middle). Both alcohol has similar chemical properties. While the third isomer, methyl ethyl ether, have significant differences in the properties of the two molecules before. This compound is not an alcoholic, but an ether, wherein the oxygen atom attached to two carbon atoms instead of one carbon and one hydrogen as well as alcohol. Ether does not have a hydroxyl group.

There are two types of isomers, namely structural isomers and stereoisomers. Structural isomers are isomers that differ from the arrangement / sequence of atoms bonded to each other. The examples mentioned above included into the structural isomers. While stereoisomers have the same structure, but some atom or functional group having a different geometry.
