Dear Mohammed,

The chemical shift of the proton in the hydrazide derivatives varies according to the solvent and the nature of the surrounding group.

For examples, use the following link:

In addition, the hydrazide proton can exchange with solvents such as H2O (D2O):

For more information on the exchange, please use the following link:

Hoping this will be helpful,

Dear Mohammed ,

Usually NH2 proton appears at 4 to 5 ppm region in 1H NMR, sometimes it goes to downfield depends on nature of substituents of NH2
