Question

Which of these represents the best lewis structure for acetylene (c2h2)?

Answer 1

Answer:

• The best lewis structure for the acetylene is as following

                                    H---C≡C----H

Explanation:

• Each carbon has four valence electrons
• Each Hydrogen has two valence electron
• Total valence electrons are 10.
• 3 lines between two carbons atoms show 8 valence electrons
• Two hydrogen atoms show 2 valence electrons

Geometry:

• Linear lewis structure

Summary:

• The best lewis strcuture of acetylene consist of one triple bond between two carbons atoms and two single bonds with each hydrogen atoms.
