FAQs on JEE Main 2025-26 Hydrocarbons Mock Test: Ultimate Practice Guide
1. What are hydrocarbons?
Hydrocarbons are organic compounds made up of only carbon and hydrogen atoms. They are classified into categories such as alkanes, alkenes, and alkynes based on the type of bond between carbon atoms. Hydrocarbons occur naturally in fuels like petroleum and natural gas.
2. How do you test for hydrocarbons in the laboratory?
To test for the presence of unsaturated hydrocarbons (like alkenes and alkynes), the bromine water test is commonly used. The brown color of bromine water disappears when it reacts with unsaturated hydrocarbons due to addition reactions. Saturated hydrocarbons like alkanes do not react with bromine water under normal conditions.
3. What are the main types of hydrocarbons?
Hydrocarbons are mainly classified as:
• Alkanes (saturated, single bonds)
• Alkenes (unsaturated, one double bond)
• Alkynes (unsaturated, one triple bond)
They can also be separated into acyclic (open-chain) and cyclic (closed-chain) hydrocarbons.
4. What is the general formula for alkanes, alkenes, and alkynes?
Alkanes: CnH2n+2
Alkenes: CnH2n
Alkynes: CnH2n-2
In these, n = number of carbon atoms.
5. What is cracking of hydrocarbons?
Cracking is a chemical process where large hydrocarbon molecules are broken down into smaller, more useful molecules by applying heat and sometimes a catalyst. It is widely used in the petroleum industry to produce petrol, diesel, and other fuels.
6. What is isomerism in hydrocarbons?
Isomerism occurs when compounds have the same molecular formula but different structural formulas or arrangements of atoms. In hydrocarbons, this is seen in alkanes and alkenes, leading to different physical and chemical properties despite identical compositions.
7. How are hydrocarbons important in daily life?
Hydrocarbons are essential as fuels (like CNG, LPG, petrol, diesel), raw materials for plastics, synthetic fibers, pharmaceuticals, and various industrial chemicals. Their combustion releases energy vital for transportation and domestic use.
8. What are aromatic hydrocarbons?
Aromatic hydrocarbons are a type of cyclic hydrocarbon containing one or more benzene rings. They are characterized by delocalized pi electrons and unique stability known as aromaticity. Examples include benzene, toluene, and naphthalene.
9. What are the chemical properties of alkenes?
Alkenes are unsaturated hydrocarbons containing at least one double bond. Their key chemical properties include:
• Addition reactions (e.g., with hydrogen, halogens, water)
• Combustion forming CO2 and H2O
• Polymerization to form plastics and fibers
10. How can you distinguish between alkanes and alkenes experimentally?
Alkanes and alkenes can be distinguished using the bromine water test or Baeyer's test (cold dilute potassium permanganate). Alkenes decolorize bromine water and turn Baeyer's reagent from purple to colorless, while alkanes show no reaction.
11. What is the significance of hydrocarbons in the industrial sector?
Hydrocarbons serve as primary sources for energy production and are fundamental in manufacturing chemicals, fertilizers, plastics, and synthetic fibers. The petroleum and natural gas industries rely on hydrocarbons for refining, synthesis, and powering machinery.
12. List common sources of hydrocarbons.
Major sources of hydrocarbons include petroleum, natural gas, coal, and biomass. These natural sources are processed to obtain fuels and raw materials for various organic compounds.
