Answer: The lewis dot structure is attached below.
Explanation:
A Lewis dot structure is defined as the representation of atoms having electrons around the atom where electrons are represented as dots.
A ketene is an organic compound having general formula R′R″C=C=O, where R and R' are two different/same monovalent chemical groups.
The given chemical compound having formula [tex]C_2H_2O[/tex] is represented as [tex]H_2-C=C=O[/tex].
Total number of unshared electrons = 4 (left on oxygen atom only)
The lewis dot structure of [tex]C_2H_2O[/tex] is given in the image below.
