Concept explainers
Interpretation: The structure of tetramethylammonium ion has to be drawn. Tetramethylammonium ion has a permanent positive charge; the reason behind this should be determined.
Concept introduction:
Depending on the number of carbon side chain of the nitrogen, different types of amines can form.
In a quaternary ammonium ion a nitrogen atom with four attached groups is positively charged. And their compounds are known as quaternary ammonium salt.
Example: Tetramethylammonium ion
