Organic Chemistry Short Notes Download Organic Chemistry Organic chemistry is the study of compounds containing carbon with the exception of simple compounds. For an example carbonates (CO32-), carbon dioxide (CO2) and carbon monoxide (CO). Nomenclature There are over 6 million known organic compounds. Nomenclature is therefore very important. Here are some basic guidelines that should help in the naming of the simple compounds you will come across during this subject. 1) Find the longest carbon chain in the molecule. This will give you the base of the name: 2) Determine the principle functional group and its position. Position is indicated, where necessary, by numbering the carbons in the main chain. Position need not be indicated for alkanes, asthey have no functional group, and aldehydes and acids, as they are terminal functional groups. Positioning numbers are flanked by dash signs. Multiple positions for a given functional group are s...
