Answer : The three-dimensional structure of ethanol is shown below.
Explanation :
The ethanol molecule is made up of 2 carbon atoms, 6 hydrogen atoms and 1 oxygen atom.
The 3D representation is shown by solid, dash and wedge bonds.
Dash lines shows that the molecules are behind the plane.
Wedge shows that the molecules are above or front of the plane.
Solid line shows that the molecules are present on the plane.
