Question

If L.P.G gas contains butane having molecular formula ${C_4}{H_{10}}$ , name the possible products, when it undergoes complete combustion.

Answer 1

Hint: First we will learn about the chemical and the physical properties of Butane and then we will learn about the term combustion. And lastly, with the help of proper reactions procedures, we will learn about the products formed when Butane undergoes complete combustion.

Complete step-by-step answer:
Butane is an alkane, having the molecular formula ${C_4}{H_{10}}$.
At room temperature and atmospheric pressure, it is present in the form of gas.
Highly flammable, colorless, easily liquefied gas and highly volatile at room temperature.
Butane is a colourless gas with an astringent smell.

Frostbite is caused when it contacts with a liquid.

It is easily ignited and its vapours are heavier than air.

It leaks either in liquid or vapour form.

Under prolonged exposure to fire or intense heat the containers may blast and damage seriously.

It is commonly used as a fuel in aerosol as propellant, in cigarette lighters, and to make other chemicals.

Possible products that are obtained by the complete combustion of butane are carbon dioxide and water molecules.
Combustion reactions are the reactions in which hydrocarbon decomposes in the presence of air having oxygen to produce carbon dioxide and water molecules are called Combustion reactions.

Reaction:
$2{C_4}{H_{10}}\left( g \right)\,\,\, + \,\,\,13{O_2}\left( g \right)\,\, \to \,\,8C{O_2}\left( g \right)\,\, + \,\,10{H_2}O\left( l \right)$
{When 2 moles of butane react with 13 moles of oxygen it produces 8 moles of carbon dioxide and 10 moles of water.}

NOTE - The name butane is derived from butyric acid. In 1849, it was discovered by the British chemist Edward Frankland who found it dissolved in crude petroleum. On complete combustion, and are the possible products. Combustion reactions are exothermic reactions which take place between a fuel and an oxidant and produce oxidised products.
