1h NMR spectrum of an aldehyde C5H8O?

i need to know the structure of this aldehyde. only 1h nmr is given there is a 3H with 3 peaks at 1ppm, 2H Quartet at 2ppm, 1H-2peaks at 6ppm, 1H-6peaks at 6.8ish ppm, and 1H 1peak at 9.8ish ppm I get the part where the 9.8ish ppm being the aldehyde group and 1ppm and 2ppm being CH2-CH3-R but i do not... show more i need to know the structure of this aldehyde.
