Chapter 9: Problem 141

In 1999 an unusual cation containing only nitrogen \(\left(\mathrm{N}_{5}^{+}\right)\) was prepared. Draw three resonance structures of the ion, showing formal charges. (Hint: The \(\mathrm{N}\) atoms are joined in a linear fashion.)

Short Answer

Expert verified
The three resonance structures of the \(\mathrm{N}_{5}^{+}\) ion have been drawn showing formal charges. In each structure, the positive charge is moved from one nitrogen atom to the next in the linear structure.

Step by step solution

01

Understand the Structure

Firstly, you need to understand the basic structure of the cation which is linear. This means that all Nitrogen atoms are interconnected in a straight line.
02

Drawing First resonance structure

Draw the first resonance structure, place a positive charge on one of the terminal nitrogen atoms. Place a triple bond between the first two nitrogens and a single bond with the third one. Continue with single bonds for the remaining atoms.
03

Drawing Second resonance structure

For the second structure, transfer the proton from the first atom to the second one, thus shifting the positive charge to the second atom. Keep the remaining structure same.
04

Drawing Third resonance structure

Continue this trend for the third resonance structure moving the positive charge to the third nitrogen atom.
