Answer #1

Particular functional group has unique chemical shift due to density of electron .Here as defined substituent X ,Y and Z have unique chemical shift range in ¹HNMR spectrum.

Z =( aldehyde proton ) Chemical shift ranges from 8.5 -9.5 ppm

y = (Aromatic proton ) Chemical shift ranges from 7.0-8.0 ppm

x = (aliphatic proton ) chemical shift ranges from 1.0-1.8 ppm

So, based on chemical shift, highest to lowest effective field in the ¹HNMR spectrum is

z $\large >$ y $\large >$ x
