Identification of the ring or chain with the maximum number of senior groups. Identification of the ring or chain with the most senior elements (In order: N, P, Si, B, O, S, C). Identification of the parent compound. Rings are senior to chains if composed of the same elements. For cyclic systems: Identification of the parent cyclic ring.
A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z). [ 1 ] The definitive visualisation of all 118 elements is the periodic table of the elements , whose history along the principles of the periodic law was one of the founding ...
Name this longest root chain using standard naming rules; Name each side chain by changing the suffix of the name of the alkane from "-ane" to "-yl" Number the longest continuous chain in order to give the lowest possible numbers for the side-chains [10] Number and name the side chains before the name of the root chain
A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics.
A three-carbon chain with the -OH on the second carbon would be propan-2-ol. Note that in some instances, common names are better. If the -OH is on the end of the chain, or the carbon chain is only 1 or 2, use no number. Use standard Greek prefixes to name molecules with two or more -OH groups (di- for 2, and so on). [1]
The main carbon chain is the longest possible continuous chain. The chemical affix denotes what type of molecule it is. For example, the ending ane denotes a single bonded carbon chain, as in "hexane" (C 6 H 14). [30] Another example of IUPAC organic nomenclature is cyclohexanol: Cyclohexanol. The substituent name for a ring compound is cyclo ...
Numbering of the carbon chain always begins at one bridgehead atom (where the rings meet) and follows the carbon chain along the longest path, to the next bridgehead atom. Then numbering is continued along the second longest path and so on. Fused and bridged bicyclic compounds get the prefix bicyclo, whereas spirocyclic compounds get the prefix ...
