How many and wgat are the Word roots of nomenclature in organic chemistry

Question

Arun · Answer

The word root represents the number of carbon atoms in the parent chain. For the chains upto four carbon atoms special word roots are used whereas for the chains containing more than four carbon atoms, Greek numerals (Table 1) are used. The word roots for different carbon chains are derived by leaving ‘ane’ from the name of carbon chain of respective molecule. Some unbranched Chains and their Names Name Number of Carbon Atoms Structure Methane 1 CH 4 Ethane 2 CH 3 CH 3 Propane 3 CH 3 CH 2 CH 3 Butane 4 CH 3 (CH 2 ) 2 CH 3 Pentane 5 CH 3 (CH 2 ) 3 CH 3 Hexane 6 CH 3 (CH 2 ) 4 CH 3 Heptane 7 CH 3 (CH 2 ) 5 CH 3 Octane 8 CH 3 (CH 2 ) 6 CH 3 Nonane 9 CH 3 (CH 2 ) 7 CH 3 Decane 10 CH 3 (CH 2 ) 8 CH 3 Undecane 11 CH 3 (CH 2 ) 9 CH 3 Dodecane 12 CH 3 (CH 2 ) 10 CH 3 Tridecane 13 CH 3 (CH 2 ) 11 CH 3 Tetradecane 14 CH 3 (CH 2 ) 12 CH 3 Pentadecane 15 CH 3 (CH 2 ) 13 CH 3 Hexadecane 16 CH 3 (CH 2 ) 14 CH 3 Heptadecane 17 CH 3 (CH 2 ) 15 CH 3 Octadecane 18 CH 3 (CH 2 ) 16 CH 3 Nonadecane 19 CH 3 (CH 2 ) 17 CH 3 Eicosane 20 CH 3 (CH 2 ) 18 CH 3 Heneicosane 21 CH 3 (CH 2 ) 19 CH 3 Docosane 22 CH 3 (CH 2 ) 20 CH 3 Tricosane 23 CH 3 (CH 2 ) 21 CH 3 Triacontane 30 CH 3 (CH 2 ) 28 CH 3 Hentriacontane 31 CH 3 (CH 2 ) 29 CH 3 Tetracontane 40 CH 3 (CH 2 ) 38 CH 3 Pentacontane 50 CH 3 (CH 2 ) 48 CH 3 Hexacontane 60 CH 3 (CH 2 ) 58 CH 3 Heptacontane 70 CH 3 (CH 2 ) 68 CH 3 Octacontane 80 CH 3 (CH 2 ) 78 CH 3 Nonacontane 90 CH 3 (CH 2 ) 88 CH 3 Hectane 100 CH 3 (CH 2 ) 98 CH 3 The word root of one carbon chain is obtained by leaving ane from methane i.e., meth–and similarly for others e.g. C1 Methane Meth- C2 Ethane Eth-
