Hydrocarbons
हाइड्रोकार्बन
In this Class 10 Science topic from Carbon and its Compounds, students learn how hydrocarbons are formed only from carbon and hydrogen and how their covalent bonding creates different structures. The topic introduces saturated and unsaturated hydrocarbons, homologous series, basic naming, molecular and structural formulae, and the role of single, double, and triple bonds. Students also connect these ideas with combustion, addition, and substitution reactions to understand the properties and uses of common carbon compounds.
