Answer 1

Answer:

1.3 this is the answer of the questions

Answer 2

The approximate value of methyl proton in NMR is 1.3.

• The full form of NMR is Nucleus magnetic resonance spectroscopy.
• The approximate value of methyl proton in NMR is 1.3 ppm.
• This value is not constant in every case. If some electron-withdrawing group is attached to it then the proton experience deshielding and shows a higher chemical shift value.
• If some electron-donating group is attached to it then the proton experiences shielding and show a lower chemical shift value.
• Hence the correct option is A.
