NMR chemistry

The reference used 1H NMR is a deuterium atom

• True

• False

The number of signals in 1H NMR represents

• non-equivalent protons

• equivalent protons

• number of electrons

• number of neutrons

The spin-spin splitting is due to...

• any protons

• adjacent protons

• total number of electrons

• nucleus

Area under a signal is due to...

• number of protons

• non-equivalent protons

• number of electrons

• equivalent protons

Proton NMR works due to resonating nucleus under the influence of radio frequency

• true

• false

Hydrogen atom in OH, NH2, SH and COOH are called?

• unreactive

• non-polar

• labile proton

• non-labile proton

What does TMS stands for?

Draw the structure of "TMS"

Answer explanation

Why is TMS Used?

• Its less volatile hence it does not change state quickly

• Gives multiple sharp peaks and easily detected adsorption

• Resonates at a field strength well aove that of any H nuclei

What are the advantages of using CCL4, CoCl3, as solvent in MMR

• Non-polar

• NMR-active

• Has no protons
