A process in which large molecules are broken up into into smaller molecules is called as_____.
Correct answer: B. Cracking
- A. Reforming
- B. Cracking
- C. Refining
- D. Isomerization
Explanation
Cracking is the thermal or catalytic decomposition of large hydrocarbon molecules into smaller alkanes and alkenes. The likely wrong choice is reforming, which changes the structure of hydrocarbons, especially to branched or aromatic forms, rather than simply breaking them into smaller molecules.

About Alkanes
Alkanes are saturated hydrocarbons containing only carbon-carbon and carbon-hydrogen single bonds, with the general formula CnH2n+2 for open chains. Their structure, isomerism, IUPAC nomenclature, physical properties, combustion, free-radical halogenation and conformations are covered, including the difference between substitution in alkanes and addition in unsaturated hydrocarbons.
