Step-by-step explanation:
Confirmational Analysis of Isopentane
To answer your questions regarding isopentane, here is a detailed response:
a) Confirmatory Tests for Isopentane
Confirmatory tests for isopentane, or any organic compound, typically involve spectroscopic methods such as Nuclear Magnetic Resonance (NMR) spectroscopy, Infrared (IR) spectroscopy, Mass Spectrometry (MS), and Gas Chromatography (GC). These analyses can confirm the structure and purity of the compound.
b) Isomeric Structure of Isopentane
The compound in the middle of the given structural formulas is isopentane; it has a one CH3 branch off the second carbon atom of the continuous chain. The isomeric structure of isopentane, also known as 2-methylbutane, has a branching point at the second carbon atom when numbering the longest carbon chain.
c) Physical Properties of Isopentane
Some physical properties of isopentane include a boiling point of 27.7°C, which is different from its other isomers due to its unique structure. As a hydrocarbon, isopentane is flammable and has a lower boiling point compared to the straight-chain pentane.
d) Reaction Mechanisms Involving Isopentane
Isopentane can undergo various chemical reactions characteristic of alkanes, such as combustion, halogenation, and isomerization. For example, the combustion of isopentane will produce carbon dioxide and water, while the halogenation can yield different alkyl halides depending on the conditions.
