NCERT Class 10 Science Chapter 4 Carbon and its Compounds
Class 10 Science Carbon and its Compounds let you know that most of the substances around us, including us, are made up of carbon compounds. Our exhaustive NCERT Solutions for Class 10 Science Chapter 4- Carbon and its Compounds give you an in-depth conceptual clarity. Some of the concepts covered here have been discussed below.
- Bonding in Carbon – The Covalent Bond
This part of the chapter tells you that a carbon atom has a valency of four and it shares its valence electrons with other atoms like carbon, hydrogen and other elements to complete its octet and the resultant bond is known as a covalent bond.
- Versatile Nature of Carbon
This part of NCERT CBSE Class 10 Science Chapter 4 lets you know about the unique property of carbon called catenation, which is the formation of long-chain structures of carbon atoms bonded through covalent bonds. This chapter further tells you that, as carbon has a valency of four, it can make covalent bonds with four different atoms at a time to give a wide variety of compounds and these bonds are strong bonds ensuring the stability of the compounds formed.
- Saturated and Unsaturated Carbon Compounds
This part of the chapter tells you that two carbon atoms can be joined through three different types of bond- first, when two carbon atoms share only one pair of electron between them to give a single bond and hence a saturated compound; second, the formation of unsaturation compounds when two carbon atoms either share two pairs of electrons to form a double bond or share three pairs of electrons to form a triple bond.
- Chains, Branches and Rings
This portion tells you that carbon chains formed by forming covalent bonds between carbon atoms can exist in the form of straight chains, branched chains (alternative arrangement of a straight-chain compound) or rings.
- Homologous series
In this portion of CBSE NCERT Class 10 Science Chapter 4, you learn that family of compounds formed by the addition of a particular carbon-containing unit each time is known as homologous series. In homologous series, the same functional group is attached to carbon chains of different lengths. It further tells you that there is a general formula to depict a homologous series and there is a gradation in physical properties.
- Nomenclature of carbon compounds
The names of carbon compounds in a homologous series are derived from the name of the basic carbon chain modified by a “prefix” or “suffix” indicating the nature of the functional group.
- Chemical properties of carbon compounds
This chapter tells you about most of the fuels we use are carbon compounds. It further lets you learn about the types of chemical reactions shown by carbon compounds. It teaches you about combustion reactions which are reactions of carbon compounds with oxygen giving out carbon dioxide, water, heat and light. It elaborates about the oxidation of carbon compounds using oxidising agents to obtain carboxylic acid.
This chapter also explains about additional reactions of unsaturated carbon compounds where hydrogen atoms are added across the double and triple bonds. It gives you a brief about the substitution of hydrogen atoms by halogen atoms in the presence of sunlight to give haloalkane.
- Some Important Carbon Compounds Ethanol and Ethanoic acid
This topic of the chapter tells you about two commercially important compound ethanol and ethanoic acid and their physical and chemical properties.
- Soaps and Detergents
The last topic of chapter 4 of CBSE NCERT Class 10 Science book explains the mechanism lying behind the action of soaps and detergents that is based on the presence of both hydrophobic and hydrophilic groups in the molecule, helping to emulsify the oily dirt and hence its removal.
