**Educational Content on Isomeric Structures and NMR Spectroscopy****Set #1:**Four isomeric structures are shown with the molecular formula C₅H₁₀O:- Structure a: CH₃CH₂CH₂C(=O)CH₃- Structure b: CH₃CH₂C(=O)CH₂CH₃- Structure c: CH₃CH₂CH₂CH₂C(=O)CH₂- Structure d: Cyclopentanone with an OH group (cyclopentanol)**Question:**Which isomer shows 3 peaks in its ¹³C-NMR spectrum, none of which is very far downfield?**Set #2:**Four isomeric structures with the same molecular formula C₅H₁₀O:- Structure a: CH₃CH₂CH₂C(=O)CH₃- Structure b: CH₃CH₂C(=O)CH₂CH₃- Structure c: CH₂=CHCH₂CH₂CH₂OH- Structure d: Cyclohexanone (structure with an ether linkage forming a six-membered ring)**Question:**Which isomer shows 3 peaks in both its ¹H and ¹³C NMR spectra?**Explanation:**NMR spectroscopy is a technique used to observe the behavior of atomic nuclei in a magnetic field, providing insight into the structure of organic compounds. In ¹³C-NMR, carbon atoms in different environments show distinct peaks. A similar principle applies to ¹H-NMR, but it focuses on hydrogen atoms. Structures can be assigned based on the number and position of peaks, reflecting the symmetry and unique chemical environments present in the isomers.

Different types of peaks in NMR shows different environment around that atom. Protons with same…
