Question
Open chain hydrocarbons and closed chain hydrocarbons.
✓
Answer
- A hydrocarbon in which the chain of carbon atoms is not cyclic is called an open chain hydrocarbon.
- All aliphatic hydrocarbons contain open chains.
Closed chain hydrocarbons:
- A hydrocarbon in which the chain of carbon atoms is present in a cyclic form or ring form is called a closed chain hydrocarbon.
- All aromatic hydrocarbons contain closed chains.
