Question

A compound C₄H₉Br gave the following ¹H NMR spectrum: triplet,

\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, which matches the structure of CH3CH2CHBrCH3. The multiplet at 4.1 ppm indicates a proton adjacent to a bromine atom, consistent with the CHBr group in this structure.
