Question

wich of the following is intern refrens standard use in NMR spectroscopy​

Answer 1

Explanation:

Tetramethylsilane

Tetramethylsilane became the established internal reference compound for 1H NMR because it has a strong, sharp resonance line from its 12 protons, with a chemical shift at low resonance frequency relative to almost all other 1H resonances.
