Deduce the structure of an unknown compound using the data below: molecular formula: c6h12o ir: 1705 cm-1 1h nmr: no absorptions greater than δ 3 ppm 13c nmr: δ 24.4, δ 26.4, δ 44.2, and δ 212.6 ppm. resonances at δ 44.2 and 212.6 have very low intensity.

City a and city b had two different temperatures on a particular day. on that day, four times the temperature of city a was 8â° c more than 3 times the temperature of city b. the temperature of city a minus twice the temperature of city b was â’3â° c. what was the temperature of city a and city b on that day? city a was 5â° c, and city b was 4â° c. city a was 3â° c, and city b was â’1â° c. city a was 8â° c, and city b was â’3â° c. city a was 5â° c, and city b was â’5â° c.
