Question

how many molecules of acetylene are required to form benzen?​

Answer 1

Dear Student,

◆ Answer -

3 molecules of aectylene are required for preparation of benzene.

● Explaination -

Acetylene molecule is represented as C2H2 and benzene by C6H6.

Reaction for formation of benzene is -

3 CH≡CH --> C6H6

Red hot iron tube is used as catalyst for this reaction.

From this we can say that - 3 molecules of aectylene are required for preparation of benzene.

Thanks dear. Hope this helps you...

Answer 2

Three molecules of acetylene are required to form benzene.

Explanation:

• Benzene is an organic compound with the chemical formula $C_6H_6$.

• It is found in crude oil and gasoline. It is a colourless and high inflammable chemical.

• Acetylene is a hydro carbon with the chemical formula $C_2H_2$. It is used as fuel and unstable in pure form.

• Benzene is prepared from acetylene by the cyclic polymerization process.

• While the acetylene is passed through a red hot iron tube, it undergoes polymerisation and forms benzene.

• Reaction for formation of benzene is -

        3CH≡$CH\rightarrow C_6H_6$.
