Question
**1H NMR Chemical Shift Question** **Question:** What is the \( ^1H \) NMR chemical shift value (in ppm) of the indicated hydrogen? **Diagram:** - The diagram shows a chemical structure with three phenyl rings arranged in a tripod-like shape. - The indicated hydrogen (shown in red) is attached to the central carbon, which is bonded to the three phenyl rings. **Choices:** - ○ 5.41 ppm - ○ 8.41 ppm **Explanation:** In this question, you are tasked with determining the appropriate \( ^1H \) NMR chemical shift value for the hydrogen atom indicated within the aromatic compound. Consider factors like the electronic environment and shielding/deshielding effects to assess the chemical shift.
