Reaction Chart of Alkanes

Understanding the Reactions of Alkanes — CBSE | JEE | NEET Perspective

Alkanes, also known as saturated hydrocarbons, are foundational in organic chemistry and form the basis for understanding more complex reaction mechanisms. Although alkanes are relatively less reactive compared to other functional groups, their reactions—especially combustion, halogenation, cracking, and substitution—are frequently tested in CBSE board exams, JEE Main/Advanced, and NEET preparation.

This reaction chart of alkanes summarizes the major transformations of alkanes into halogenated products, alkenes, and other derivatives under specific conditions. Knowing these reactions helps students tackle:

Mechanism-based MCQs

Reaction prediction questions

Stepwise conversion problems


Important concepts linked with alkanes include:

The free radical mechanism in halogenation

Selectivity and reactivity order (tertiary > secondary > primary)

Energy profiles of radical chain reactions

Industrial processes like cracking and reforming


To strengthen your command on this topic, revise related sections such as free radical substitution mechanism, bond dissociation energy trends, and stability of alkyl free radicals. Understanding alkanes thoroughly builds confidence for advanced topics in organic synthesis and improves performance in both competitive and board exams.
