How can the following reaction be described?
C8H18 → C4H10 + 2C2H4
A combustion
B cracking
C oxidation
D reduction
Answer: B
Explaination
Cracking is a process in which long carbon chain alkane molecules broken up into smaller molecules.
Here in the above equation, a single large alkane molecule octane (C8H18) undergo cracking to produce butane (C4H10) molecule and ethene (C2H4) molecules.
