An unknown X shows a broad absorption and in the infrared at 23200-3550 cm-1 but none in the 1620-1780 cm-1 region. It contains only C, H, and O. A 116 mg sample was treated with an excess of methylmagnesium bromide, producing 48.7 mL of methane gas collected over mercury at 20 oC and 750 mm Hg. The mass spectrum of X has its molecular ion (barely detectable) at 116 m/z and a fragment peak at 98. What does this information tell you about the structure of X
