This PPT contains a wonderful and colourful and which yearly enquiry slides of the introduction to organic chemistry in class 10 CBSE which is the fourth lesson in the science NCERT textbook which is carbon and its compound.
•Carbon is oneof the most important elements found in nature, forming the basic building block of
all living organisms.
•Its ability to form long chains and rings, known as catenation, makes it highly versatile for creating
various compounds.
•Carbon compounds are found everywhere: in fuels we burn for energy, in the food we eat, in
medicines that heal us, and in materials like plastics and synthetic fibers.
•Understanding carbon chemistry helps us explain the structure and function of many everyday
substances.
Introduction
4.
•Carbon is tetravalent,meaning it can form four covalent bonds with
other atoms, allowing it to make complex molecules.
•It has the property of catenation, which enables it to link with other
carbon atoms to form long chains, branched chains, or rings.
•Carbon can form single, double, and triple bonds, which leads to a huge
variety of chemical compounds.
•Its allotropes, like diamond, graphite, and fullerenes, show completely
different physical properties, even though they are made of the same
element.
Properties of Carbon

•Diamond: Diamond isthe hardest naturally occurring substance. It
has a crystal lattice structure and is used in cutting tools, jewelry,
and industrial drills.
•Graphite: Graphite is soft and slippery due to layers of carbon
atoms that can slide over each other. It is a good conductor of
electricity and is used in pencils, lubricants, and batteries.
•Fullerenes and Nanotubes: Fullerenes are spherical molecules of
carbon, while carbon nanotubes are cylindrical.

Hydrocarbons
Hydrocarbons are compoundsmade exclusively of carbon and hydrogen atoms.
They form the foundation of organic chemistry and are widely used as fuels and raw
materials.
Types of Hydrocarbons:
Alkanes: Saturated hydrocarbons with single bonds, general formula CnH2n+2, e.g.,
Methane (CH₄), Propane (C₃H₈).
Alkenes: Unsaturated hydrocarbons with at least one double bond, general formula CnH2n,
e.g., Ethene (C₂H₄).
Alkynes: Unsaturated hydrocarbons with at least one triple bond, general formula CnH2n-2,
e.g., Ethyne (C₂H₂).
Hydrocarbons are important as fuels, lubricants, and chemical feedstock in industries.
7.
Structural Representations
Carbon compoundscan be represented using molecular formulas (showing the
number of atoms) or structural formulas (showing the arrangement of atoms).
Example: Methane (CH₄) shows one carbon atom bonded to four hydrogen atoms
in a tetrahedral shape.
Ethene (C₂H₄) has a double bond between two carbon atoms, while Ethyne (C₂H₂)
has a triple bond, giving unique chemical properties.
Using structural diagrams helps in understanding reactions, functional groups, and
isomers of carbon compounds.
8.
Nomenclature (IUPAC Rules)
IUPACprovides a systematic way to name carbon compounds to
avoid confusion.
The longest carbon chain in a molecule is identified as the parent
chain.
Prefixes indicate the number of carbon atoms, and suffixes (-ane, -
ene, -yne) show the type of bond present.
Example: Methane (CH₄), Ethene (C₂H₄), Propane (C₃H₈), Butyne
(C₄H₆).
Proper naming allows scientists and students worldwide to
communicate chemical structures clearly.
9.
Functional Groups
Functional groupsare specific groups of atoms in a molecule that
determine its chemical properties.
Common examples:
Alcohol (-OH): Found in drinks and antiseptics.
Carboxylic Acid (-COOH): Found in vinegar and citric acid.
Aldehyde (-CHO): Used in perfumes and flavorings.
Ketone (>C=O): Used in solvents and pharmaceuticals.
Functional groups explain why different carbon compounds have
different chemical behaviors even if they contain the same number
of carbon atoms.
10.
Important Reactions ofCarbon
Compounds
Combustion: Hydrocarbons react with oxygen to produce carbon dioxide and
water, releasing energy.
Oxidation: Alcohols can be oxidized to carboxylic acids, e.g., ethanol acetic
→
acid.
Addition Reactions: Alkenes and alkynes can add hydrogen, halogens, or
water across multiple bonds.
Substitution Reactions: Halogens replace hydrogen atoms in alkanes, e.g.,
CH₄ + Cl₂ CH₃Cl + HCl.
→
These reactions are the basis of many industrial and laboratory processes.
11.
Uses of CarbonCompounds
Fuels: Petrol, diesel, LPG, and natural gas are carbon-based hydrocarbons
used for energy.
Medicines: Carbon compounds form the backbone of many drugs,
vitamins, and antibiotics.
Plastics and Polymers: PVC, polythene, and synthetic fibers are made from
carbon compounds.
Alcohols and Acids: Used in industries for making soaps, detergents,
solvents, and preservatives.
Carbon compounds are essential in almost every sector of human life.
12.
Environmental Concerns
Carbon compounds,especially from burning fossil fuels, can cause
pollution and health hazards.
Carbon monoxide (CO): A poisonous gas that binds with hemoglobin
in blood, reducing oxygen transport.
Carbon dioxide (CO₂): Excess emission leads to global warming and
climate change.
Sustainable alternatives, such as biofuels and renewable energy, are
necessary to reduce environmental impact.

Conclusion & References
Carbonis a versatile and essential element, forming the
backbone of all living organisms and many materials.
Its ability to form diverse compounds makes it indispensable
in fuels, medicines, plastics, and industrial applications.
