Question

Answer

In organic chemistry, an alkane, or paraffin (a historical name that also has other meanings), is an acyclic saturated hydrocarbon. In other words, an alkane consists of hydrogen and carbon atoms arranged in a tree structure in which all the carbon–carbon bonds are single. Alkanes have the general chemical formula CnH2n+2. The alkanes range in complexity from the simplest case of methane (CH4), where n = 1 (sometimes called the parent molecule), to arbitrarily large and complex molecules, like pentacontane (C50H102) or 6-ethyl-2-methyl-5-(1-methylethyl)octane, an isomer of tetradecane (C14H30)

Answer

Alkanes are compounds consisting of carbon and hydrogen with only single bonds connecting them throughout the compound.They are also called saturated hydrocarbons.
Alkanes are used for many purposes.
Some of the common uses are : Heating , electricity generation ,cooking, production of polymers, making of drugs ,pesticides and other chemicals and in paraffin wax.
The usage can be differentiated according to the number of carbon atoms in the alkane.

Answer

It generally y consists of butane , propane and ethane .And both of these belongs to alkane series

Answer

The correct answer is option 'A', alkane.

Explanation:
Cooking gas, also known as liquefied petroleum gas (LPG), is mainly composed of alkane compounds. Alkanes are hydrocarbons that consist of only carbon and hydrogen atoms, and they are characterized by the presence of single bonds between carbon atoms.

Here is a detailed explanation of why cooking gas is primarily an alkane:

1. Composition of LPG:
LPG is a mixture of gases that are liquefied under high pressure. The main components of LPG are propane (C3H8) and butane (C4H10), which are both alkanes. These alkanes are present in high concentrations and serve as the primary source of fuel for cooking in households.

2. Properties of alkanes:
Alkanes are known for their low reactivity due to the presence of only single bonds. They are generally colorless, odorless, and flammable. These properties make alkanes suitable for use as a clean-burning fuel.

3. Energy content:
Alkanes have a high energy content, which is released when they undergo combustion. When LPG is burned, it produces a significant amount of heat energy, making it an efficient fuel for cooking purposes.

4. Safety considerations:
One of the reasons why alkanes like propane and butane are commonly used as cooking gas is their safety profile. They are stored in pressurized containers, which makes them easy to handle and transport. Additionally, these gases have a narrow flammability range, reducing the risk of accidental ignition.

5. Combustion process:
When alkanes are burned in the presence of oxygen, they undergo complete combustion, resulting in the production of carbon dioxide (CO2) and water (H2O). This combustion process is highly efficient and does not produce significant amounts of pollutants or harmful byproducts.

In conclusion, the cooking gas used in our homes is primarily an alkane. Alkanes, such as propane and butane, have the necessary properties for efficient and safe combustion, making them ideal for cooking purposes.
