The staggered form of butane in which the bulky methyl groups on the two carbons are placed on opposite sides, that is, at a dihedral angle of 180°, is the lowest energy, most stable form — called the anti conformer. This conformation is stabilized due to the absence of steric repulsion between the largely spaced out methyl groups.

Butane Chemical Formula

The geometry of the molecule is tetrahedral with all the carbon atom being sp 3 and having bonds of 109 of angle. Butane also has a isomer, called methyl butane with the formula CH 3 (CH)CH 3 CH 4 . Its chemical structure can be written as below, in the common representations used for organic molecules.

Difference Between Butane and Isobutane

15/4/2012· Melting point of butane is 133-139 K, and the boiling point is 272-274 K. Butane is the common name used to indie all the molecules with this formula. There are two structural isomers that we can draw to match this formula but, in IUPAC nomenclature, we use butane specifically to indie unbranched molecule, which is also known as n-butane.

Initial boiling point: 15F at 1 bar. Dew point: 24F at 1 bar. Specific heat: 0.549 Btu/lb at 60F; 2.299 kJ/kg at 15.6C.

Butane - an overview ScienceDirect Topics

Butane is one of two saturated hydrocarbons, or alkanes, with the chemical formula C4 H 10 of the paraffin series. In both compounds, the carbon atoms are joined in an open chain. In n -butane (normal), the chain is continuous and unbranched, whereas in i -butane (iso) the carbon atoms form a side branch.

Rotation of eclipsed by an angle of 180-degree results in anti- conformer. The rotation of anti butane by an angle of 120 degrees produces a gauche conformer. Staggered Conformation of Butane The conformers study primarily involves the arrangement of either groups or atoms concerning the central atom.

Butane - Wikipedia

Density The density of butane is highly dependent on temperature and pressure in the reservoir. [9] For example, the density of liquid phase is 571.8±1 kg/m 3 (for pressures up to 2MPa and temperature 27±0.2 C), while the density of liquid butane is 625.5±0.7 kg/m 3 (for pressures up to 2MPa and temperature -13±0.2 C).
