What is the word equation for combustion of a hydrocarbon?

The reaction typically gives off heat and light as well. The general equation for a complete combustion reaction is: Fuel + O2 → CO2 + H2O.

What are aliphatic and aromatic hydrocarbons with examples?

Aliphatic compounds are those hydrocarbons that are the open chain compounds and also closed chains. Aromatic compounds are those who have only a closed chain structure. Examples for aliphatic compounds are methane, propane, butane etc. Examples for aromatic compounds are benzene, toluene etc.

What is the chemical equation for hydrocarbon?

The main component of natural gas is the hydrocarbon called methane (CH4). You can see a methane flame in the Figure below. The combustion of methane is represented by the equation: CH4 + 2O2 → CO2 + 2H2O.

What is the main reaction of aromatic hydrocarbon?

Aromatic compounds or arenes undergo substitution reactions, in which the aromatic hydrogen is replaced with an electrophile, hence their reactions proceed via electrophilic substitution.

What is complete combustion of hydrocarbons?

Complete combustion happens when there is a good supply of air. Carbon and hydrogen atoms in the hydrocarbon fuel react with oxygen in an exothermic reaction: carbon dioxide and water are produced.

What is the general formula of aromatic compounds?

The aromatic compounds or arenes are having the general formula of \[{C_n}{H_{2n – 6m}}\]where n is the number of atoms present and m is the number of rings. – Aromatic compounds will undergo nucleophilic and electrophilic reactions. – Aromatic compounds are said to be aromatic because they follow Huckel’s rule.

What is the general formula for aromatic hydrocarbons?

Aromatic compounds with two or more fused aromatic benzene rings are called polycyclic aromatic hydrocarbons (PAH) and they have the general formula C4r+2H2r+4 for rings without substituents, where r = number of rings.

What is the molecular formula for benzene?

C6H6
Benzene/Formula
Benzene is an important organic chemical compound with the chemical formula C6H6 and its molecule is composed of 6 carbon atoms joined in a ring with 1 hydrogen atom attached to each carbon atom.

What is combustion in chemistry?

combustion, a chemical reaction between substances, usually including oxygen and usually accompanied by the generation of heat and light in the form of flame.

What is the structure of aliphatic and aromatic hydrocarbons?

Structure of Aliphatic and Aromatic Hydrocarbons. Aliphatic Hydrocarbons: They have straight chains, branched chains or non-aromatic rings in their structure. This group has both saturated and unsaturated hydrocarbons.

What is the chemical equation for benzene and limonene?

For benzene and limonene, you can write above reaction replacing (6,6) and (10,16) for (x,y), respectively. , Expert for chemistry. Benzene: C6H6 + 7 1/2O2 —> 6CO2 + 3H2O, if it burns in oxygen defficient environment CO is produced.

How do you find the formula of a hydrocarbon?

This allows investigators to find the formula of any organic hydrocarbon by measuring the carbon dioxide and water it produces on complete combustion. Aliphatic hydrocarbons do not contain delocalised electron systems (benzene rings, primarily). They can be sub-divided into straight chains, branched chains.

Are aliphatic hydrocarbons flammable?

Most aliphatic hydrocarbons are flammable. These compounds can be found in crude oil and as natural gases. Cyclic compounds can be also considered as aliphatic hydrocarbons. This is because those cyclic structures are non-aromatic (no delocalized pi electrons).
