Question

osazone is produced by reacting glucose molecule with x molecule of phenylhydrazine..
what is the value of x .

Answer 1

Osazone is produced when glucose reacts with 3 moles of Phenyl hydrazine

First mole adds to the CHO part of glucose giving hydrazone (-CH=N-NH-Ph)

The latter two moles turn the C-2 carbon to hydrazone (-CH=N-NH-Ph)
