Answer:
<u>CH</u>
Explanation:
Molecular formula of propene : <u>C₃H₆</u>
Take the HCF of carbon and hydrogen atoms :
Then, we can write the formula as :
- 3CH
- This means there are 3 moles present
Empirical Formula :
- Molecular Formula / No. of moles
- C₃H₆ / 3
- <u>CH</u>
<u></u>
The empirical formula of propene is <u>CH</u>
