Question

The approximate \( \delta \) value of methyl proton in \( ^{1}H \) NMR is:

• A. \( \text{1.3} \)
• B. \( \text{1.5} \)
• C. \( \text{0.9} \)
• D. \( \text{2.5} \)

Hint:

Chemical shift values in \( ^{1}H \) NMR help identify functional group environments in organic molecules.

Answer 1

The Correct Option is C

The chemical shift (\(\delta\)) of a methyl (-CH\(_3\)) proton in \( ^{1}H \) NMR typically falls around 0.9 ppm, depending on substituents and molecular environment. Other values represent different functional groups or electronic influences.
