According to the potential maps for ammonium ion, which atom has the greatest electron density?

Short Answer

Expert verified

The nitrogen atom in the ammonium ion has the greatest electron density.

Step by step solution

01

Understanding potential maps

Potential maps are a representation of charge distributions in a molecule. It consists of different colors which signify different charge densities. Red is for the most negative electrostatic potential and blue stands for the most positive electrostatic potential.

02

Analyzing the potential map of ammonium ion.

The red color indicates maximum electron density. According to the potential maps of ammonium ions, the nitrogen atom has the maximum red thus nitrogen has the greatest electron density in ammonium ion.

The following compound has only one asymmetric centre. Why then does it have four stereoisomers?

An atom with a formal charge does not necessarily have more or less electron density than the atoms in the molecule without formal charges. We can see this by examining the potential maps for H20,H3O+ and HO-.

  1. Which atom bears the formal negative chargein the hydroxide ion?
  2. Which atom has greater electron density in the hydroxide ion?
  3. Which atom bears the formal positive charge in the hydronium ion?
  4. Which atom has the least electron density in the hydronium ion?
