What is Acetylene?

C2H2 is easiest alkyne chemistry compound v chemical name Acetylene.

You are watching: What is the molecular formula of acetylene?

Acetylene is also called Ethyne or Narcylen or Vinylene. That is extensively used as a chemical building block and as a fuel. In that is pure form, that is rough is taken on as a solution. That is one unsaturated link the two carbon atoms in it room linked along with a double bond.

Vinylene is a colourless gas which has a mild ether-like odour. The is easily soluble in water, chloroform, acetone, and also benzene. The is slightly soluble in carbon disulfide and ethanol. It is lighter when contrasted to air and also easily ignites. Prolonged exposure to warm or fire can rupture containers violently.

Chemical properties of Acetylene (C2H2)

1. Reaction v HBr

When acetylene is treated with HBr, the product is Ethylidene bromide.


2. Reaction v sodium metal

Sodium reacts with acetylene to produce sodium hydro acetylide and hydrogen.

Na + C2H2 → NaHC2 + H2

3. Reaction with HCl

When acetylene reacts with HCl, CH3CHCl2 is formed.


Acetylene Uses

Acetylene is offered brazing.Used in the glass industry.Used in the manufacturing of man-made rubber.Used in soldering metals.Used as an additive to maintain food.Used come precipitate metals.Used come manufacture acetic acid.Used as a feedstock in the production of acrylonitrile.Used in carburization the steel.Used together a fuel additive.

Production of Acetylene

Since the year 1950, this compound has been synthesized through the partial burning of CH4 (methane). Approximately 4,00,000 tonnes was developed until 1983.

In the year 1862, the was all set by a reaction i beg your pardon was discovered by Friedrich Wohlerthe. Hydrolysis the calcium carbide reaction is as follows:

CaC2 + 2H2O → Ca(OH)2 + C2H2

The above reaction takes ar in an extremely high temperature approximately 2000 °C, with the use of an electrical arc furnace.

Health Hazards

People who come in call with this compound might suffer native headache, ns of consciousness, and also dizziness. Fatality due come choking can occur if a greater percentage the Ethyne is current in the air.

Frequently Asked concerns – FAQs

What is acetylene provided for?

Acetylene is supplied in welding and cutting processes. The welding process using acetylene is recognized as cut oxy-fuel or cutting coal. This technique is provided for cutting or welding products which call for temperatures of approximately 3,500 ° C (6,330 ° F). Acetylene is capable of producing the hottest fire of all various other gases.

How acetylene is produced?

Acetylene is created by any of 3 methods: through the reaction the water v calcium carbide, by passing through an electrical arc of a hydrocarbon, or by partial burning of methane through air or oxygen;

Why is Ethyne called acetylene?

The surname was invented by French chemist Marcelin-Pierre-Eugène Berthelot (1823-1907) in 1864, native the French acétylène. This was derived from the chemical finishing ene + acetyl, i beg your pardon the German chemist Justus von Liebig coined the acetic in 1839.

What happens if friend inhale acetylene?

Symptoms of inhalation that acetylene incorporate dizziness, fatigue, tiredness, nausea, vomiting, tachycardia and tachypnea<2>. Exposure come a high level of acetylene will lead to a lose of consciousness and death. Acetylene is a colourless gas widely provided in welding processes.

Is acetylene corrosive come metal?

Acetylene is colourless in that pure form, and also has a an excellent scent. When it has several functions, acetylene is now recognized as being qualified of inhibiting top-line corrosion usually developing in gas pipelines. It deserve to be sprayed as a corrosion inhibitor, fan to the high volatility.
