What are the rules for naming organic compounds?Ans: Following are the rules for writing naming organic compoundsRule 1: Find the longest continuous chain of carbon atoms and use its name as the base name for the compound.Rule 2:Beginning with the end of the chain closest to a substituent, number the longest chain.Rule 3:If a substituent appears more than once, the prefix di, tri, or tetra is used with the location of the carbon on which it appears.Rule 4:Write the alkyl groups in alphabetical order regardless of their position on the chain.Rule 5:Cyclic hydrocarbon has the prefix cyclo before the name. Thus, the IUPAC name of this compound is Methane. There are 3 chlorine atoms substituted onto the ring in the 2, 4 and 6 positions. For chains from one to four carbon atoms, special word roots (based upon the common names of alkanes) are used, but for chains of five or more carbon atoms, Greek number roots are used as given below: Note: Extra a given in parenthesis is used only if the primary suffix to be added to the word root starts with a constant. These are the compounds in which carbon atoms are joined to form one or more rings with or without heteroatom. Hydroquinone (1,4-benzenediol) is a particularly easy compound to oxidize, because it has two hydroxyl groups in the proper relationship to give up hydrogen atoms to form a quinone.
