Alkanes are hydrocarbons that consist of only carbon and hydrogen atoms and are saturated compounds. In other words, all the carbon atoms are linked by single bonds, and each carbon atom has as many hydrogen atoms as possible.
Here are some key concepts and topics related to alkanes that you should cover as part of your JEE (Main+Advanced) integrated course:
- Nomenclature: You should be able to name alkanes according to IUPAC rules. This includes identifying the longest carbon chain, assigning a parent name, and using prefixes to indicate substituents or functional groups.
- Isomerism: Alkanes exhibit structural isomerism, where different compounds have the same molecular formula but different arrangements of atoms. You should be able to identify and name different types of isomers, such as chain isomers, positional isomers, and functional group isomers.
- Conformational Analysis: Alkanes can exist in different conformations due to the rotation around single bonds. You should be able to identify different conformations, such as eclipsed, staggered, and gauche conformations, and understand the relative stability of each.
- Physical Properties: Alkanes are generally nonpolar and have low boiling and melting points. You should understand the factors that affect the physical properties of alkanes, such as molecular weight, branching, and intermolecular forces.
- Reactions: Alkanes are relatively unreactive due to their strong carbon-carbon and carbon-hydrogen bonds. However, they can undergo combustion, halogenation, and other substitution reactions under certain conditions. You should be able to describe the mechanisms and conditions for these reactions.
- Cycloalkanes: Cycloalkanes are cyclic alkanes that have unique properties and reactivity. You should be able to name and draw different cycloalkanes, understand their strain energies and conformations, and describe their reactions.
- Stereochemistry: Although alkanes do not have stereocenters, they can exhibit stereochemistry due to the presence of chiral or prochiral centers. You should be able to identify and describe the stereochemistry of different compounds, such as cis-trans isomers and enantiomers.
Overall, a thorough understanding of alkanes is important for success in JEE (Main+Advanced) chemistry. It is essential to master the fundamental concepts, practice naming and drawing compounds, and apply the concepts to solve problems and answer questions.

IUPAC System naming of JEE (Main+Advance) Integrated Course Alkanes
The IUPAC system for naming alkanes involves a systematic method for naming organic compounds based on their molecular structure. The basic steps involved in the IUPAC system for naming alkanes are:
- Identify the longest continuous chain of carbon atoms in the molecule. This is known as the parent chain.
- Number the carbon atoms in the parent chain from the end nearest a substituent. This ensures that the substituent has the lowest possible number.
- Identify and name the substituents, which are groups of atoms that are attached to the parent chain. Substituents are named using prefixes such as methyl, ethyl, propyl, butyl, etc.
- Combine the names of the substituents with the name of the parent chain to form the complete name of the compound.
The prefixes used to name the substituents are as follows:
- Meth- for a one-carbon substituent (methyl)
- Eth- for a two-carbon substituent (ethyl)
- Prop- for a three-carbon substituent (propyl)
- But- for a four-carbon substituent (butyl)
- Pent- for a five-carbon substituent (pentyl)
- Hex- for a six-carbon substituent (hexyl)
- Hept- for a seven-carbon substituent (heptyl)
- Oct- for an eight-carbon substituent (octyl)
- Non- for a nine-carbon substituent (nonyl)
- Dec- for a ten-carbon substituent (decyl)
For example, consider the alkane with the molecular formula C6H14. The longest continuous chain of carbon atoms in this molecule contains six carbon atoms, so the parent chain is hexane. If there is a methyl group attached to the second carbon atom, the name of the compound is 2-methylhexane. If there is an ethyl group attached to the third carbon atom, the name of the compound is 3-ethylhexane.
The IUPAC system for naming alkanes provides a systematic way to name organic compounds and is widely used in the chemical industry and in scientific research.

- Identify the parent chain: The parent chain is the longest continuous chain of carbon atoms in the molecule. The parent chain gives the root name of the compound.
- Number the parent chain: Number the carbon atoms in the parent chain from the end closest to the first substituent. This ensures that the lowest possible numbers are assigned to the substituents.
- Identify and name the substituents: Substituents are groups of atoms that are attached to the parent chain. Name the substituents as prefixes and add them to the root name. The prefix is based on the number of carbon atoms in the substituent. Common substituents include methyl (1 carbon), ethyl (2 carbons), propyl (3 carbons), and butyl (4 carbons).
- Number the substituents: Number the substituents based on the carbon atom to which they are attached. If there are multiple substituents, list them in alphabetical order.
- Write the name: Combine the name of the substituents and the name of the parent chain, with the substituents listed in alphabetical order.
For example, the IUPAC name for a molecule with a parent chain of six carbon atoms and a methyl substituent attached to the second carbon atom is “2-methylhexane.”
