One is n-butane and the other is iso-butane. Linear Formula (CH 3) 3 CH . Butane and isobutane, for example, both have the molecular formula C 4 H 10 . A chemical formula is a way of presenting information about the chemical proportions of atoms that constitute a particular chemical compound or molecule, using chemical element symbols, numbers, and sometimes also other symbols, such as parentheses, dashes, brackets, commas and plus (+) and minus (−) signs. Butane, or C4H10, has two structural (also called constitutional) isomers called normal butane, or unbranched butane, and isobutane, or i-butane.
CH 3-CH 2-CH 2-CH 3. The 2D chemical structure image of ISOBUTANE is also called skeletal formula, which is the standard notation for organic molecules. The chemical formula of Isobutane, perfluoro- shown above is based on the molecular formula indicating the numbers of each type of atom in a molecule without structural information, which is different from the empirical formula which provides the numerical proportions of atoms of each type. Chem. Butane is a gas at room temperature and atmospheric pressure. Butane has a melting point of 135.4K and 2-methylpropane [isobutane] has a melting point of 114K. The boiling point of Butane is 272.6K and isobutane @ 261K. PubChem Substance ID 24857785. Uses. Chemical formula of ISOBUTANE It has the following structure. It is an alkane and a gas molecular entity. The molecular formula for butane is C 4 H 10. Construction of isomers of C 5 H 12: A structural formula shows all the carbon and hydrogen atoms and the bonds attaching them. EC Number 200-857-2.

Isobutane. It is easily ignited. Isobutane has a tertiary carbon, and it is the simplest molecule with a tertiary carbon. Contact with the liquid can cause frostbite. Isobutane is an alkane that is propane substituted by a methyl group at position 2. Structural isomers have same molecular formula but different structural formula. It may replace ozone depleting compounds that are used it refridgeration. Isobutane is a colorless, odorless, transparent gas. Relevant identified uses of the substance or mixture and uses advised against Use of the substance/mixture : Industrial use; Use as directed. By reaction with methanol and ethanol, it is a precursor to the gasoline oxygenates methyl tert-butyl ether (MTBE) and ethyl tert-butyl ether (ETBE), respectively.
It is very important to note that all of the following structures are one and same and indicate the different ways of writing the structure of isobutane. A structural isomer is one of two or more molecules that have the same molecular formula but different bond structures. Isobutane, synonymous with 2-methyl propane and trimethyl methane, is a saturated hydrocarbon with the formula: CH CH-CH3 3-~ CH3 2. Beilstein/REAXYS Number 1730720 . For transportation it may be stenched. n-Butane and Isobutane Page 3 Table 3. The chemical formula of butene is C 4 H 8 and is an alkene, meaning it has a double bond somewhere in the molecule.
It is shipped as a liquefied gas under its own vapor pressure. : 75-28-5 Formula : C4H10 / (CH3)2CHCH3 Other means of identification : 2-methylpropane, trimethylmethane, refrigerant gas R600a 1.2. By reaction with methanol and ethanol, it is a precursor to the gasoline oxygenates methyl tert-butyl ether (MTBE) and ethyl tert-butyl ether (ETBE), respectively.
Soc., 1940, 62, 2059-2063. It has the same molecular formula as butane, but the structural formula is different. According to IUPAC nomenclature, these isomers are called simply butane and 2-methylpropane. The arrangements of atoms and the shapes of the molecules, however, are different.
