Please see the attached file.

We are given 3 modified glucose structures in which a nitrogen (via amine reaction) has been placed in the glucose structure.

We are asked to determine how and what the ionic charge is around the nitrogen ion in each of the 3 cases shown.

How is the charge determined specifically around these nitrogen ions? Cationic, neutral, or anionic?

Solution Summary

Provides steps necessary to determine the ionic charge in nitrogen.

Solution Preview

Formal charge on each nitrogen atom can be determined using the formula
Formal charge = Valency of the atom - Number of lone pairs of electrons on the atom - ½ number of bond pairs of electrons
