\( \newcommand\) • • • • • • • • • • • • • • • The names of all alkanes end with -ane. Whether or not the carbons are linked together end-to-end in a ring (called cyclic alkanes or cycloalkanes) or whether they contain side chains and branches, the name of every carbon-hydrogen chain that lacks any double bonds or functional groups will end with the suffix -ane. Alkanes with unbranched carbon chains are simply named by the number of carbons in the chain. The first four members of the series (in terms of number of carbon atoms) are named as follows: • CH 4 = methane = one hydrogen-saturated carbon • C 2H 6 = ethane = two hydrogen-saturated carbons • C 3H 8 = propane = three hydrogen-saturated carbons • C 4H 10 = butane = four hydrogen-saturated carbons Alkanes with five or more carbon atoms are named by adding the suffix -ane to the appropriate numerical multiplier, except the terminal -a is removed from the basic numerical term. Hence, C 5H 12 is called pentane, C 6H 14 is called hexane, C 7H 16 is called heptane and so forth. Straight-chain alkanes are sometimes indicated by the prefix n- (for normal) to distinguish them from branched-chain alkanes having the same number of carbon atoms. Although this is not strictly necessary, the usage is still common in cases where there is an important difference in properties between the straight-chain and branched-chain isomers: e.g. n-hexane is a neurotoxin while its branched-chain isomers are not.

Why does neopentane have a higher melting point than n-pentane? I know that we can say that, due to stacking, it has a higher melting point as it freezes easily. But then, why doesn't this happen in the case of n-hexane too? n-Hexane has a melting point of −95 °C whereas 2,2-dimethylbutane has a melting point of −98 °C. Instead, if we go by stacking, 2,2-dimethylbutane should have a higher melting point. Many symmetrical molecules undergo a phase change before they melt. This is usually interpreted as the ability to rotate without disrupting the lattice structure. This has a much greater effect on the entropy of the solid than on its energy. This reduces the entropy of fusion more than it reduces the enthalpy of fusion, thereby raising the melting point which equals delta-H/delta-S. This is very dramatic in the comparison of melting points of octane, cyclo-octane, and bicyclo-octane.

Pentane Formula: Pentane is the fifth homologue of the alkane series. It is a gasoline odour, easily liquefied gas with achemical formulaof \(\)and its chemical structure is shown below. Pentane Molar Mass The molar mass of Pentane, \(\) hybridised. The ground state of each carbon atom in a pentane molecule has two electrons in its \(2,\) in each carbon atom that overlaps and form singly paired hybrid orbitals. These hybrid orbitals readily accept electrons from other atoms and form a sigma bond. Hence, in Pentane (five carbon atoms), there are twenty \(\) sigma bonds. This is diagrammatically represented as below- Pentane Molecular Geometry In Pentane \(.\) Pentane Dipole Moment Pentane is a non-polar molecule because there is no electronegativity difference between the four \(\) isless than \(0.4.\) There are no polar bonds present in Pentane. Hence, Pentane is non-polar. Pentane Lewis Structure Lewis structuresorelectron dot structures arediagramsthat represent the distribution of valence electrons of atoms within a molecule. Eachdotrepresents an electron, and a pair of dots between chemical symbols for atoms represents a bond. Total number of valence electrons \( = 5\) (Valence electrons of carbon) \( + 12\) (Valence electron of hydrogen) \( = \;5\left( 4 \right) + 12\left( 1 \right) = 32\) valence electrons. These \(32\) valence electrons are distributed as follows. In the diagram above, the octet and duplet of carbon and hydrogen atoms are satisfied, respectively. Pe...

This one carbon is part of an Common Common "Iso" can also indicate that the Common Common The prefix " neo" is used when all but two carbons form a continuous chain, and these two carbons are part of a terminal tert-butyl group.

Although the information has been compiled from what Air Liquide believes are reliable sources (International Standards: Compatibility of cylinder and valve materials with gas content; Part 1- Metallic materials: ISO11114-1 (March 2012), Part 2 - Non-metallic materials: ISO11114-2 (April 2013), it must be used with extreme caution and engineering judgement. No raw data such as these can cover all conditions of concentration, temperature, humidity, impurities and aeration. It is therefore recommended that this table is only used to identify possible materials for applications at high pressure and ambient temperature.
