Does NH[SUB]3[/SUB] react with aldehyde ?

  1. Nov 24, 2014 #1
    does NH3 react with compounds having aldehydic group?(if,yes.why doesn't glucose react with NH3. 0.02% of glucose has open chain structure that has free aldehydic group) In my textbook its given that NH3 doesn't react with glucose and this led to the conclusion that glucose had ring structure with no free aldehydic group.

    Ammonia (or amines) plus aldehydes do react to form imines; the reaction is acid catalyzed (pH dependent), and pH of the "0.02% open chain glucose" might interfere.
