Question

I determined the molecular formula of a compound to be C6H8O by using the rule of 13 for a molecular ion of m/z=96. This gives me a DBE (or index of hydrogen deficiency =3. My C13 NMR indicates a carbonyl group and peaks in the alkene region. My H NMR shows 4 peaks, 1.9ppm,singlet,3H,2.1ppm, quartet,2H,3.0ppm, triplet 2H, and 6.4ppm,triplet, 1H. Can you help me?
