15.20—Both low and high resolution proton NMR spectroscopy to: i predict the different types of proton present in a molecule

Be able to use both low and high resolution proton NMR spectroscopy to: i predict the different types of proton present in a molecule, given values of chemical shift, δ ii relate relative peak areas, or ratio number of protons, to the relative numbers of 1H atoms in different environments iii deduce the splitting patterns of adjacent, non-equivalent protons using the (n+1) rule and hence suggest the possible structures for a molecule iv predict the chemical shifts and splitting patterns of the 1H atoms in a given molecule.

Use —both low and high resolution proton nmr spectroscopy to: i predict the different types of proton present in a molecule to connect the rule to the data and decision in the question.

This matters because —both low and high resolution proton nmr spectroscopy to: i predict the different types of proton present in a molecule determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply —both low and high resolution proton nmr spectroscopy to: i predict the different types of proton present in a molecule to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: —Both low and high resolution proton NMR spectroscopy to: i predict the different types of proton present in a molecule is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
