Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Explain how you would deduce the molecular structure of a compound given its mass spectrum displaying a clear molecular ion peak and multiple fragment peaks.

💡 Hint: Use both mass-to-charge ratios and known fragment characteristics (e.g., specific m/z values) to support your deductions.

Challenge 2 Hard

You are presented with a mass spectrum showing a prominent M+ peak and a relative abundance of isotope peaks. How would this assist in determining the number of carbon atoms in the compound?

💡 Hint: Remember the formula for estimating carbon counts using isotope intensity ratios.
