\[ \mathrm{C}_2 \mathrm{H}_6 \stackrel{4500^{\circ} \mathrm{C}}{\longrightarrow} \mathrm{C}_2 \mathrm{H}_4+\mathrm{H}_2 \] Above reaction is called as
- A combustion
- B rearrangement
- C pyrolysis
- D cleavage
Answer & Solution
Correct Answer
(C) pyrolysis
Step-by-step Solution
Detailed explanation
Decomposition of a compound by application of heat is called pyrolysis and pyrolysis of higher alkanes into a mixture of lower alkanes, alkenes, etc. is also called cracking.
