**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.

We are given with the compound triphenylmethane. We need to find the chemical shift value of the indicated H on methane. In triphenylmethane, there are only two types of H atoms, which are at indicated H on methane and all other H at benzene rings. The H at benzene rings shows a multiplet peaks at 7.4 to 6.8. The indicated H on methane gives a sharp singlet at 5.5 ppm. So the answer is first option. That is, 5.41 ppm.
