Answer
Do not draw carbons and the hydrogens attached to it, instead join the lines. Show oxygen. The following is the line structure for the compound:
Work Step by Step
In a line-angle structure, carbons and the hydrogens attached to it, are not drawn. Instead presence of carbon is indicated by crossing lines or the end or beginning of the lines.
In this structure draw the structure by joining lines in the lewis structure. Since the two chains of $CH_3CH_2$ are connected to the same carbon, the following shape of the line-angle structure is obtained. Show the double bond in Oxygen.
