To draw the three-dimensional representation of the oxygen-bearing. The carbon atom in ethanol first determines the geometry of that carbon atom by drawing its line bond structure which is represented as:

Ethanol

The oxygen-bearing carbon atom of ethanol makes four single bonds, so it ishybridised and has a tetrahedral geometry. By drawing two of the carbon atom’s bonds with solid lines to represent bonds in the plane of the page, which is depicted as follows:

Bonds in the plane of the page

By drawing one bond with dashed lines to represent a bond that goes back behind the plane of the page, defined as:

By drawing one bond with a heavy wedged line to represent a bond that comes out of the plane of the page.

. This is the three-dimensional representation of the oxygen-bearing carbon of ethanol.
