Show hintHide hint
Think about molecules that share the same formula but look different.
Question 2.
What is an example of chain isomerism?
Show hintHide hint
Consider the carbon backbone structure.
3Question 3.
What is structural isomerism?
- Isomerism that involves same molecular formula but different structures
- Isomerism involving different molecular formulas
- Isomerism that is only geometric
- All molecules with same atoms are identical
Show hintHide hint
Think about different ways atoms can connect.
4Question 4.

- True
- False
Show hintHide hint
Revisit where functional groups can be placed on a carbon chain.

Given the formula C5H12, identify the possible structural isomers and describe their structures.
Show hintHide hint
Consider how you can arrange five carbons in different configurations.
Question 6.
For the formula C3H6O, identify examples of both a positional isomer and a functional group isomer.
Show hintHide hint
Think of how the positioning of the hydroxyl group changes the compound.
