Chapter 2: Alkanes. Alkanes from Carbon and Hydrogen Alkanes are carbon compounds that contain only single bonds. The simplest alkanes are hydrocarbons – compounds that contain only carbon and hydrogen.

2-Amino-5-formyl-3-hydroxypentan-1-oic acid Let us now study how such compounds are named: Principal functional group In a polyfunctional compound, one of the functional groups is selected as the principal functional group while all other functional groups are treated as substituents. Action replay max ps2 update usb download. Functional groups according to their priorities are listed in the priority table in decreasing order i.e., Carboxylic acid with the highest priority is placed at the top while alkyne being the least in priority is placed at the bottom.

• NR9, Vocalizer and NSS error logs and diagnostic logs are all saved in the NSS log files.

The functional group which has the highest priority among all the functional groups present in an organic compound is selected as the principle functional group.

Nomenclature of Organic Compounds The system of naming organic compounds is termed as nomenclature of organic compounds. The following systems are used for naming organic compounds. • Common system or trivial system • IUPAC ( International Union of Pure and Applied Chemistry) system Common System The common name of an organic compound is the general name given to the compound.

Common name system does not follow rules of any formal system. IUPAC System There are millions of organic compounds present on earth; therefore, we cannot remember all of them by their common names. To overcome this problem, a better and systematic nomenclature system has been introduced. This system is known as IUPAC system.
