The molecular formula is $C_5H_{10}O$. For the lewis structure: Draw a carbon wherever two lines meet and, a line begins and ends. Draw the two lines as double bond. And then add the number of hydrogens so that each carbon has four bonds.
1) Draw a carbon wherever two lines meet and, a line begins and ends. 2) Draw a double bond with O and two lone pairs on O. 3) Then add the hydrogens so that each carbon has four bonds. 4) Count the number of C, H and O. In this structure there are 5 Carbons, 10 hydrogens and 1 Oxygen. Thus, the molecular formula is $C_5H_{10}O$.
