- Compound I (C11H14O2) is insoluble in water, aqueous acid, and aqueous NaHCO3, but dissolves readily in 10% Na2CO3 and 10% NaOH. When these alkaline solutions are acidified with 10% HCl, compound I is recovered unchanged. Given this information and its 1H-NMR spectrum, deduce the structure of compound I.arrow_forward07) The proton NMR spectrum of a compound with formula C5H12O2 is shown below. THE The carbon-13 NMR spectrum has three peaks, respectively at 15 ppm, 63 ppm and 95 ppm. Based on this information draw the structure of this compound.arrow_forwardA compound with molecular formula C3H8O produces a broad signal between 3200 and 3600 cm³¹ in its IR spectrum and produces two signals in its 13C NMR spectrum.
