Final answer:
In a 1H NMR spectrum, the predicted splitting patterns for protons are determined by the neighboring protons. The three main types of splitting patterns are singlet, doublet, and multiplet.
Step-by-step explanation:
In a 1H NMR spectrum, the predicted splitting patterns for protons are determined by the neighboring protons. The three main types of splitting patterns are singlet, doublet, and multiplet.
A singlet occurs when there are no neighboring protons and the proton being analyzed does not split any adjacent protons.
A doublet occurs when a proton is next to one neighboring proton. The proton being analyzed is split into two peaks of equal intensity.
A multiplet occurs when a proton is next to multiple neighboring protons. The proton being analyzed is split into multiple peaks of varying intensity.
