The following is a list of straight-chain alkanes, the total number of isomers of each (including branched chains), and their common names, sorted by number of carbon atoms. [ 1 ] [ 2 ] Number of C atoms
Four-carbon molecules are based on a skeleton made from four carbon atoms. They may be in a chain, branched chains, cycles or even bicyclic compounds C 4 H 4 isomers with CAS registry numbers. Hydrocarbons that include four atoms are: butane C 4 H 10; isobutane C 4 H 10; but-1-ene C 4 H 8; but-2-ene C 4 H 8; but-1-yne C 4 H 6; but-2-yne C 4 H 6 ...
Identify the longest continuous chain of carbon atoms; 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]
Fatty alcohols (or long-chain alcohols) are usually high-molecular-weight, straight-chain primary alcohols, but can also range from as few as 4–6 carbons to as many as 22–26, derived from natural fats and oils. The precise chain length varies with the source. [1] [2] Some commercially important fatty alcohols are lauryl, stearyl, and oleyl ...
Crotonic acid has 4 carbons, is included in croton oil, and is a trans-2-mono-unsaturated fatty acid. C 3 H 5 CO 2 H, IUPAC organization name (E)-but-2-enoic acid, trans-but-2-enoic acid, numerical representation 4:1, n-1, molecular weight 86.09, melting point 72–74 °C, boiling point 180–181 °C, specific gravity 1.027. CAS registry number ...
C 4 Cl 4 O: perchlorocyclobutenone: 3200-96-2 C 4 CoF 3 O 4 Si: trifluorosilylcobalt tetracarbonyl: 15693-79-5 C 4 Dy: dysprosium tetracarbide: 12543-88-3 C 4 F 4 O 3: tetrafluorosuccinic anhydride: 699-30-9 C 4 F 6 O: hexafluorocyclobutanone: 699-35-4 C 4 F 8: octafluorocyclobutane: 115-25-3 C 4 F 10 O 2 S: nonafluorobutanesulfonyl fluoride ...
The side chains are: an ethyl- at carbon 4, an ethyl- at carbon 8, and a butyl- at carbon 12. Note: the −O−CH 3 at carbon atom 15 is not a side chain, but it is a methoxy functional group. There are two ethyl- groups. They are combined to create, 4,8-diethyl. The side chains are grouped like this: 12-butyl-4,8-diethyl.
Alkyl radicals are often considered as a series, a progression sequenced by the number of carbon atoms involved. In that progression, Butyl (containing 4 carbon atoms) is the fourth, and the last with preferred IUPAC name derived from its history. The word "butyl" is derived from butyric acid, a four-carbon carboxylic acid found in rancid ...
