Answer:
[tex]2\text{ : 2 single bonds to carbon and 1 double bond to a carbon}[/tex]Explanation:
Here, we want to describe the correct Lewis diagram for the molecule
For the molecule, we will have a double bond between the two central carbon atoms. Then, we will have 2 single bonds from each carbon atom to the hydrogen atoms.
Thus, the correct answer choice here is 2 single bonds to carbon and 1 double bond to a carbon
