Question 11 [1.4 pts] A certain proton NMR spectrum exhibits one singlet, one quartet and a number of other peaks. The height of the singlet’s “integration step” is 16 mm while the quartet’s “integration step” is 127 mm. Given that the singlet is due to one proton how many protons (expressed as a whole number) are responsible for the quartet?

exhibit in a 1H NMR spectrum. Either a Singlet, Doublet, Triplet,
Quartet, or Multiplet. They can be used once, more than once, or
none.
