The correct order that provides the most information about a chemical compound in increasing order is:
a molecular formula, a structural formula, a 3-D formula
- A molecular formula shows the number and types of atoms in a compound but does not provide information about the arrangement of those atoms.
- A structural formula gives insight into how atoms are connected, illustrating the structure of the molecule.
- A 3-D formula depicts the three-dimensional arrangement of the atoms, providing the most detailed information about the compound's geometry and spatial orientation.
So, the complete response is: a molecular formula, a structural formula, a 3-D formula.
