Answer 1

Answer #1

a) proton-A is most shielded because it is not attached to any electronegative atom.

b) Proton-D is least shielded because it attached to carbon which carries two electronegative F atom

C) proton D is most downfield due to least shielded.

d) proton-A is most upfield due to most shielded.
