Problem: Label each proton with the predicted splitting pattern it would exhibit in a 1H NMR spectrum. Either a Singlet, Doublet, Triplet, Quartet, or Multiplet. They can be used once, more than once, or none.

FREE Expert Solution

We are asked to label each proton with the predicted splitting pattern it would exhibit in a 1H NMR spectrum

Also known as spin-spin coupling, or J-coupling, this describes the distances between different protons. 

Note: This topic can be answered with or without J-values.


Since we do not have J-values given, we'll proceed with the method below: 

Adjacent, non-equivalent protons will split each other’s magnetic response to the NMR 

□ We use the n+1 rule to determine how many splits/peaks we will achieve where n is the number of adjacent, non-equivalent protons

□ Pascal’s Triangle predicts the shape of the splits we will get
