\delta

1.0 (3H) ;doublet,

\delta

1.7;multiplet,

\delta

1.8;multiplet,

\delta

4.1 (1H)
Which is a reasonable structure for the compound?

Quizplus · Accepted Answer

The triplet at 1.0 ppm suggests a CH3 group adjacent to a CH2 group, the doublet at 1.7 ppm indicates a CH group adjacent to a CH3 group, and the multiplet at 4.1 ppm suggests a CH group adjacent to a bromine atom. This matches the structure of CH3CH2CHBrCH3.
