Answer
The line structure is shown in the picture.
Work Step by Step
Draw the lewis dot structure of the formula. Then draw the line structure. Bonds are represented by lines, and carbon atoms are assumed to be present wherever two lines meet or a line begins or ends. Oxygen and nitrogen atoms are shown, but hydrogen atoms are not usually drawn unless they are bonded to an atom that is drawn. Each carbon atom is assumed to have enough hydrogen atoms to give it a total of four bonds.
