At low temperature and pressure cracking can be done in presence of catalyst________________?

Correct answer: C. Al2O3 and SiO2

  • A. Al2O3
  • B. Fe2O3
  • C. Al2O3 and SiO2
  • D. Fe2O3 and SiO2

Explanation

Catalytic cracking converts large hydrocarbons into smaller, more useful molecules at comparatively low temperature and pressure using a silica-alumina catalyst, represented as Al2O3 and SiO2. Students may choose Al2O3 alone because alumina is one component, but the standard catalyst is the combined silica-alumina material.

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.
