<u>Answer:</u> The lewis dot structure is attached below.

<u>Explanation:</u>

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 $C_2H_2O$ is represented as $H_2-C=C=O$ .

Total number of unshared electrons = 4 (left on oxygen atom only)

The lewis dot structure of $C_2H_2O$ is given in the image below.
