4.5.3 Cracking Flashcards
1
Q
What is cracking and why is it used?
A
Crude oil tends to contain much more longer alkanes than shorter ones. However, the shorter ones are more useful. Cracking breaks down longer alkanes into smaller more useful ones.
2
Q
What conditions are needed for cracking?
A
650 degrees Celsius and aluminium oxide.
3
Q
What is the general equation for cracking?
A
Long alkane –> Shorter alkane + Alkene
