Question 1

A mass spectrum shows M$^+$ at m/z 98 and an M+1 peak at 8% of M$^+$. Estimate the number of carbon atoms in the compound.

πŸ’‘ Hint: Recall the calculations for estimating carbon from isotope peaks.

Question 2

If a compound shows a prominent M$^+$ at 100 m/z, a base peak at 50 m/z, and fragment ions at 70 m/z and 40 m/z, discuss the possible structure based on the fragment ions.

πŸ’‘ Hint: Consider how bonds might break to form those fragments.
