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

The best lewis structure for the acetylene is as following

                                    H---C≡CH

Explanation:

Each carbon has four valence electronsEach Hydrogen has two valence electronTotal 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.

Well technically there are two correct answers b and d. but for you its probably b in general.good day sir/ma'am : ) (i know not gender)
