Question 5.
Given an NMR spectrum with a singlet at 1.0 ppm (3H) and a doublet at 4.0 ppm (2H), identify possible structures and explain the reasoning.
Show hintHide hint
Examine the integration ratios to confirm hydrogen counts.
Question 6.
You encounter an unknown compound with a 1H NMR displaying a broad singlet at 1.5 ppm and a quartet at 4.0 ppm. Suggest potential functional groups.
Show hintHide hint
Focus on how each signal's chemical shift may indicate structural components.
