Question 1
What does a higher chemical shift imply about a hydrogen's environment?
- It is heavily shielded
- It is deshielded
- It indicates a saturated bond
💡 Hint: Think about what causes shifts in the spectrum.
Question 2
True or False: Integration in NMR tells us the exact number of hydrogen atoms in a molecule.
- True
- False
💡 Hint: Consider the meaning of integration.

Challenge Problems
Push your limits with challenges.
Question 1
A molecule is suspected to include both an alcohol and an aromatic ring. Given its 1H NMR shows signals at 1.1 ppm (triplet), 4.2 ppm (singlet), and 7.3 ppm (multiplet), sketch a possible structure that fits these signals.
💡 Hint: Say the chemical shifts suggest specific functional groups.
Question 2
If you have a compound with a molecular formula of C6H12 and a 1H NMR spectrum showing 3 signals at 0.9 ppm (3H), 1.3 ppm (2H), and 5.1 ppm (1H), propose a structure considering the data.
💡 Hint: Verify against molecular formula against distinct signals.
