To determine which structure is correct, a 'H NMR spectrum was acquired which exhibits six signals. One of those signals is a singlet at 1.9 ppm with an integration of 3, and another of the signals is a doublet at 0.9 ppm with an integration of 6. Using this information, identify the correct structure of the compound.
