What would be the order of the chemical shift (d values) for the compounds: CH 3 Br, CH 3 Cl, CH 3..


What would be the prescribe of the chemical transfer (d values) for the coalescences: CH3Br, CH3Cl, CH3F, CH3I in 1H-NMR? Why?

In a noble decomposition 1H-NMR of a coalescence CH3CH2CH2Cl, how frequent divide signals would you forebode from the methyl  knot, the protons in the -CH2Cl knot, and the protons of the accessible -CH2— knot?
