Drawing Isomers of Pentane and Naming Organic Compounds

There are three isomers of pentane, C5H12, with different structural formulas and condensed structural formulas.
The first isomer has a five-carbon chain with attached hydrogen atoms, resulting in CH3CH2CH2CH2CH3.
The second isomer features a four-carbon chain with the fifth carbon attached to the middle, and 12 hydrogen atoms, yielding CH3CH2CH(CH3)2.
The third isomer starts with a three-carbon chain, and the remaining carbon atoms are attached to the central carbon, with 12 hydrogen atoms, resulting in CH3CH2CCH3.
The International Union of Pure and Applied Chemistry (IUPAC) provides a systematic method for naming organic compounds, which is generally accepted internationally.
Alkyl groups have the general formula CnH2n+1, and the name of the group is formed by substituting –ane by –yl from the corresponding alkane.
The letter R is often used to represent any of the possible alkyl groups in formulas.
There are specific prefixes like "iso-" for a methyl group located on the second carbon of a carbon chain, "sec" for a functional group bonded to a secondary carbon, and "tert" for a functional group bonded to a tertiary carbon.
Primary (1°), secondary (2°), and tertiary (3°) carbon atoms are designated based on their bonding configurations.
The IUPAC rules for naming alkanes involve selecting the longest continuous chain of carbon atoms as the parent compound and numbering the carbon atoms, among other guidelines.
Cycloalkanes, which contain rings of carbon atoms, are named by placing the prefix "cyclo-" before the name of the corresponding alkane.
The text also includes exercises to practice naming and drawing structural formulas for specific alkanes, applying the concepts discussed.
