Chemical Structure and Molecular Composition
The HCOOCH CH2 H2O system involves three distinct molecular components that interact through well-defined chemical pathways.
Methyl Formate (HCOOCH₃) Structure:
- Molecular formula: C₂H₄O₂
- Functional group: Formate ester
- Molecular weight: 60.05 g/mol
