Pyrosulphuric Acid Structure Identification
Pyrosulphuric acid, also known as disulfuric acid, has the chemical formula $H_2S_2O_7$. Its structure is characterized by two sulfuric acid ($H_2SO_4$) units joined by an oxygen atom, forming a central sulfur-oxygen-sulfur (S-O-S) bridge.
The structure consists of:
- Two sulfur atoms (S).
- Seven oxygen atoms (O).
- Two hydrogen atoms (H).
- A central oxygen atom linking the two sulfur atoms.
- Each sulfur atom is bonded to the bridging oxygen, two additional oxygen atoms (one commonly depicted as a double bond), and one hydrogen atom.
The image corresponding to Option D depicts this specific arrangement, correctly representing the molecular structure of pyrosulphuric acid ($H_2S_2O_7$).
