Resonance Structures of Nitromethane
Nitromethane is a nitroalkane with the formula CH 3NO 2. It is a colorless, volatile liquid with a sweet odor. Nitromethane is used as a solvent, as a fuel additive, and as an intermediate in the synthesis of other chemicals.
Nitromethane has two resonance structures. Resonance is a concept in chemistry that describes the delocalization of electrons within a molecule. In the case of nitromethane, the electrons in the double bond between the carbon and nitrogen atoms are delocalized, meaning that they are not confined to a single bond.
To determine the correct second resonance structure of nitromethane, it is crucial to consider the concept of resonance. Resonance involves the delocalization of electrons, which affects the stability and flexibility of molecules. Similar to how different structures influence the flexibility of the extracellular matrix (link to article) , the resonance structures of nitromethane impact its overall stability and chemical properties.
This delocalization results in two resonance structures, which are shown below:

The formal charges on each atom in each resonance structure are shown in the table above. Formal charges are a way of calculating the charge on an atom in a molecule. They are not always accurate, but they can be useful for understanding the distribution of electrons in a molecule.
Determining the Correct Resonance Structure: Determine The Correct Second Resonance Structure Of Nitromethane
The correct resonance structure of nitromethane can be determined by considering the following factors:
- The number of covalent bonds
- The formal charges of the atoms
- The electronegativity of the atoms
The resonance structure with the lowest formal charges and the most covalent bonds is the most stable.
Example
The two resonance structures of nitromethane are:
- CH 3NO 2
- CH 2=NO 2–
The first resonance structure has a formal charge of 0 on the nitrogen atom and a formal charge of -1 on the oxygen atom. The second resonance structure has a formal charge of +1 on the carbon atom and a formal charge of -1 on the oxygen atom.
The first resonance structure is more stable because it has a lower formal charge and more covalent bonds.
Applications of the Correct Resonance Structure
The correct resonance structure of nitromethane can be used to predict a variety of its properties, including its reactivity, stability, and physical characteristics.
In chemical reactions, using the correct resonance structure is essential for predicting the outcome of the reaction. For example, the correct resonance structure of nitromethane can be used to predict the products of its reaction with a nucleophile. The nucleophile will attack the electrophilic carbon atom in the resonance structure that has the most positive charge, which is the carbon atom that is bonded to the nitro group.
