Isobutane, also known as i-butane, 2-methylpropane or methylpropane, is a chemical compound with molecular formula HC(CH3)3. It has 2 isomers, (have same molecular formula but differe due to structure) They are named on the basis of position of triple covalent bond, formed between 2 aadjacent carbon atoms. The general formula for an alkane is C n H 2n+2 where n is the number of carbon atoms in the molecule. Contents. It can be shown by following structural formula: Structural formula of propane can also be written as CH 3 CH 2 CH 3 or CH 3 − CH 2 − CH 3. Since butane has only 4 carbon atoms there are only two possible isomers. In butane …n-butane; the branched-chain form is isobutane.Both compounds occur in natural gas and in crude oil and are formed in large quantities in the refining of petroleum to produce gasoline.

Examples of other chemical formulae for butane are the empirical formula C 2 H 5, the molecular formula C 4 H 10 and the condensed (or semi-structural) formula CH 3 CH 2 CH 2 CH 3. Learn vocabulary, terms, and more with flashcards, games, and other study tools. 11.21 Butane and 2-methylpropane, whose space-filling models are shown, are both nonpolar and have the same molecular formula, yet butane has the higher boiling point (-0.5 °C compared to -11.7 °C ). Explain why this formula does not show the geometry of the real molecule. A study was conducted to establish whether volatile hydrocarbons, such as propane, n-butane and iso-butane, are metabolized in mice or not. Articles of 2-bromo-2-methylbutane are included as well. There is more than one way to represent a hydrocarbon formula, depending on how compact on wants to write the formula ... Write condensed formula by using general formula. Full Displayed Formula of Butane: Skeletal Formula of Butane: Pentane. A condensed structural formula for ethane may be written as: ...

For example, two alkanes have the formula C 4 H 10: They are called n-butane and 2-methylpropane (or isobutane), and have the following Lewis structures: The compounds n-butane and 2-methylpropane are structural isomers (the term constitutional isomers is also commonly used). The first four alkanes are methane (CH 4), ethane (C 2 H 6), propane (C 3 H 8) and butane (C 4 H 10). Condensed Structure Formula In condensed structure formulas, the C-H bonds are omitted and all the H atoms attached to a certain carbon (or other atoms) are usually shown as a group like CH 3, CH 2, NH 2, OH.The structures in Table 2.1 are shown as condensed structures.The C-C bond sometimes can be omitted as well (as for 2-methylpropane and 2-hexanol in the examples below). chemestry. Determine the formal charge on the nitrogen atom in each of the following structures. Butane (C 4 H 10) has two structural isomers..
