Class 10 Science - GUJARAT
Carbon and its Compounds
The chapter 'Carbon and its Compounds' in Class 10 GSEB Science explores the unique versatility of carbon, the basis of all living things and organic chemistry. Students will learn about covalent bonding, the tetravalency of carbon, and its remarkable ability to form long chains through catenation. The chapter covers homologous series, functional groups, and nomenclature of carbon compounds. It also details the chemical properties of carbon compounds like combustion and oxidation, alongside important organic molecules such as ethanol and ethanoic acid. Finally, it explains the cleansing action of soaps and detergents, holding high weightage in Gujarat Board exams.

Covalent Bonding
The chemical bond formed by the sharing of electron pairs between two atoms, allowing carbon to achieve a stable noble gas configuration without losing or gaining electrons.
Catenation
The unique property of carbon atoms to link with one another through covalent bonds to form long chains, branched chains, and rings.
Homologous Series
A series of organic compounds having the same functional group and similar chemical properties, where each successive member differs by a -CH2- unit.
Functional Groups
A specific heteroatom or group of atoms within molecules that is responsible for the characteristic chemical reactions of those molecules, such as alcohols, aldehydes, and carboxylic acids.
Saponification
The alkaline hydrolysis of esters (fats and oils) using sodium hydroxide to produce soap and glycerol.

Board Exam Info
In the Gujarat (GSEB) Class 10 Science board examination, this chapter typically carries around 6 to 8 marks. Questions frequently include IUPAC naming, structural isomerism, distinction tests for saturated and unsaturated hydrocarbons, properties of ethanol and ethanoic acid, and the micelle formation mechanism of soaps.
Frequently Asked Questions
Why does carbon form covalent bonds instead of ionic bonds?
What is the difference between saturated and unsaturated hydrocarbons?
Saturated hydrocarbons contain only single bonds between carbon atoms (alkanes), while unsaturated hydrocarbons contain one or more double or triple bonds (alkenes and alkynes).
How do soaps clean greasy clothes?
Soap molecules have a hydrophobic (water-repelling) tail that attaches to oil and grease, and a hydrophilic (water-attracting) head that dissolves in water, forming spherical structures called micelles that are washed away.
