The two models that represent molecules of substances with the same chemical formula but different arrangements of atoms are:
- Cyclopropane (C3H6)
- Propene - (C3H6)
Chemical Formula Completion:
For both substances, the chemical formula is:
- C: 3
- H: 6
So, the completed chemical formula for both substances is:
- C: 3
- H: 6
This means:
- Cyclopropane: C₃H₆
- Propene: C₃H₆
Both substances have the same molecular formula (C3H6) but differ in their structural arrangements, which is a characteristic of isomers.
