Final answer:
The expected 1 H NMR spectral data for the compound shown is 3.8 (1H, septet), 2.1 (3H, 5), 1.0 (6H, d).
Step-by-step explanation:
The 1 H NMR spectral data expected for the compound shown is option D) 3.8 (1H, septet), 2.1 (3H, 5), 1.0 (6H, d).
In the given options, this is the only one that matches the reported chemical shifts and multiplicities.
Based on the data provided, the compound has a septet at 3.8 ppm, representing a proton with six neighboring protons, a doublet at 2.1 ppm, representing three equivalent protons, and a doublet at 1.0 ppm, representing six equivalent protons.
