Carbon and its Compounds
कार्बन और उसके यौगिक
In Class 10 Science, the chapter Carbon and its Compounds explains why carbon forms a wide variety of stable substances through covalent bonding. Students study hydrocarbons, saturated and unsaturated carbon compounds, and functional groups that influence chemical properties. The chapter also introduces important reactions of carbon compounds and compares soaps and detergents, including how they work in cleaning and the limitations of soap in hard water.
1Covalent bonding
सहसंयोजक बंधन
In Class 10 Science, this topic from “Carbon and its Compounds” explains how carbon atoms form covalent bonds by sharing pairs of electrons to achieve greater stability. Students learn the difference between single, double and triple covalent bonds and relate these bond types to the structures of methane, ethene and ethyne. The topic also helps them understand why carbon forms a wide variety of compounds and how bonding influences their basic structures and properties.
12 questionsHydrocarbons
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.
17 questionsFunctional groups
क्रियात्मक समूह
In Class 10 Science, this topic from “Carbon and its Compounds” explains how specific atoms or groups of atoms in an organic molecule determine its characteristic properties and reactions. Students learn to identify common functional groups such as hydroxyl, aldehyde, ketone and carboxylic acid groups, represent them in structural formulae, and relate their presence to the naming, properties and chemical behaviour of carbon compounds.
14 questionsSoaps and detergents
साबुन और अपमार्जक
In this Class 10 Science topic from the chapter Carbon and its Compounds, students learn how soaps and detergents remove dirt and oil. They explore the structure of soap as sodium or potassium salts of long-chain fatty acids, and understand how the hydrophobic and hydrophilic ends of their molecules form micelles in water. The topic also explains saponification, the difference between soaps and synthetic detergents, and why soaps are less effective in hard water because they form scum with calcium and magnesium ions.
