### NMR Signal Analysis of Three Compounds#### Compounds Analyzed- **Compound A:** CH₃COCH₂CH₂CH₃- **Compound B:** CH₃CH₂CH₂COCH₃- **Compound C:** CH₃CH₂COCH₂CH₃#### Questions for Analysis**(a) True/False, all three compounds have the same number of ¹H NMR signals?** ______**(b) Which compound has the furthest downfield, three hydrogen singlet, (3H, singlet)?** ______**(c) Which compound lacks a two hydrogen triplet, (2H, triplet)?** ______**(d) Which compound has two unique signals that are both three hydrogen triplets, (3H, triplet)?** ______##### Explanation of Terms:- **¹H NMR (Proton Nuclear Magnetic Resonance):** An analytical chemistry technique used to determine the structure of organic compounds by observing the behavior of hydrogen atoms in a magnetic field.- **Downfield:** Refers to a signal shift to a lower magnetic field (higher chemical shift, usually measured in ppm (parts per million)).- **Singlet:** A signal with no splitting, indicating the hydrogen environment has no adjacent hydrogen atoms.- **Triplet:** A signal split into three peaks, indicating the hydrogen environment has two adjacent hydrogen atoms.This educational resource provides questions to test students' understanding of proton NMR signals in different organic compounds.
