Decoding Hydrocarbons: CBSE NCERT Downloads Unveiling the Differences Between Saturated and Unsaturated Hydrocarbons
I. Understanding Hydrocarbons:
Before we embark on distinguishing between saturated and unsaturated hydrocarbons, let's establish a foundational understanding of hydrocarbons. These compounds are primarily derived from fossil fuels and can be classified based on the type of bonding between carbon atoms.
II. Saturated Hydrocarbons:
-
Structure: Saturated hydrocarbons, also known as alkanes, feature single bonds between carbon atoms. This results in a straight or branched chain structure with each carbon atom holding a maximum number of hydrogen atoms.
-
General Formula: The general formula for saturated hydrocarbons can be expressed as CnH2n+2, where 'n' represents the number of carbon atoms.
-
Physical Properties: Saturated hydrocarbons are generally found in a state of matter ranging from gases (e.g., methane) to liquids (e.g., octane) to solids (e.g., paraffin wax). They exhibit relatively high melting and boiling points due to strong intermolecular forces.
-
Chemical Reactivity: Alkanes are known for their low reactivity. Their single bonds are stable, making them less prone to undergoing chemical reactions compared to unsaturated counterparts.
III. Unsaturated Hydrocarbons:
-
Structure: Unsaturated hydrocarbons, comprising alkenes and alkynes, feature double or triple bonds, respectively, between carbon atoms. This introduces a degree of unsaturation into the molecule.
-
General Formula: The general formula for alkenes is CnH2n, and for alkynes, it is CnH2n-2. The absence of some hydrogen atoms in comparison to alkanes is a result of the multiple bonds.
-
Physical Properties: Unsaturated hydrocarbons often exist in a gaseous or liquid state and exhibit lower melting and boiling points than their saturated counterparts. The presence of double or triple bonds introduces a degree of geometric isomerism.
-
Chemical Reactivity: Due to the presence of multiple bonds, unsaturated hydrocarbons are more reactive than saturated ones. The double and triple bonds readily undergo addition reactions, making them crucial in the synthesis of various organic compounds.
IV. Significance and Applications:
-
Saturated Hydrocarbons:
- Commonly used as fuels (e.g., gasoline and diesel).
- Serve as the primary components of waxes, lubricants, and some plastics.
-
Unsaturated Hydrocarbons:
- Essential in the production of polymers and synthetic materials.
- Act as key intermediates in the synthesis of pharmaceuticals and agrochemicals.
Difference between saturated and unsaturated compounds?
Solution
The difference between saturated and unsaturated hydrocarbons are given below:Substitution
Saturated hydrocarbons.
1. Saturated hydrocarbons are organic compounds that contain only single covalent bonds between two carbon atoms
2. Saturated hydrocarbons are known alkanes.
3. Saturated hydrocarbons are less reactive as compared to unsaturated hydrocarbons.
4. Saturated hydrocarbons burn with a blue flame
5. Saturated hydrocarbon undergoes substitution reaction.
Example: Sunstitution reaction between methane(CH4) and chlorine(Cl2).
CH4+Cl2⟶CH3−Cl+HCl
Unsaturated hydrocarbons
1. Unsaturated hydrocarbons are organic compounds that contain double and triple covalent bonds between two carbon atoms.
2. Unsaturated hydrocarbons are known as alkenes and alkynes.
3. Unsaturated hydrocarbons are more reactive due to π−electron density.
4. Unsaturated hydrocarbons burn with a sooty flame.
5. Unsaturated hydrocarbons undergo an addition reaction.
Example: Addition of hydrogenH2 to ethene(CH2=CH2)
CH2=CH2+H2⟶CH3−CH3

SAMPLE PRACTICE QUESTION
Q:1 What defines saturated hydrocarbons?
Ans: Saturated hydrocarbons, or alkanes, feature single bonds between carbon atoms, creating a saturated structure.
Q:2 How do unsaturated hydrocarbons differ?
Ans: Unsaturated hydrocarbons, including alkenes and alkynes, possess double or triple bonds, introducing unsaturation and reactivity.
Q:3 What is the general formula for saturated hydrocarbons?
Ans: The general formula is CnH2n+2, where 'n' represents the number of carbon atoms in saturated hydrocarbons.
Q:4 Contrast the physical properties of saturated and unsaturated hydrocarbons.
Ans: Saturated hydrocarbons often exist in solid or liquid states with higher melting points, while unsaturated ones are typically gases or liquids with lower melting points.
Q:5 How does chemical reactivity vary between saturated and unsaturated hydrocarbons?
Ans: Saturated hydrocarbons have lower reactivity due to stable single bonds, whereas unsaturated counterparts readily undergo addition reactions due to double or triple bonds.
