Concept explainers
Interpretation:
The species responsible for the electrostatic potential map is to be stated.
Concept introduction:
An electrostatic potential map represents electron clouds in a molecule in various colors that indicate its relative charge. Red color indicates the buildup of a negative charge, whereas the blue color indicates a buildup of a positive charge. Colors in between red and blue, in the spectrum, indicate a more neutral charge. Two equal resonance contributors for a molecule suggest equal distribution of electron density. For a given molecule, multiple resonance structures are possible which involves an atom with a lone pair of electron adjacent to the multiple bond. A carbon bearing a negative formal charge has three bond pairs and one lone pair.
