Answer:
Lewis structures are shown below
Step-by-step explanation:
- In Lewis structure of nitromethane, a negative charge is present on oxygen atom in nitro group.
- Hence this oxygen atom acts as a basic center preferably.
- Therefore conjugate acid of nitromethane should be drawn by adding a hydrogen atom with this oxygen atom.
- Lewis structure of nitromethane as well as it's conjugate acid has been shown below including all the lone pairs and formal charges
