The alkane cracking mechanism has been a subject of intense scrutiny, with carbonium and free radical mechanisms being two well-established pathways ... Cracking of alkanes involves · The correct Answer is:C · It involves the homolysis of C−C and C−H bonds, resulting in the formation of free radicals. Keywords. Cracking - Cracking is a thermal decomposition reaction where larger alkanes are broken down into smaller alkanes and alkenes. The breaking down of large hydrocarbon molecules into smaller, more useful hydrocarbon molecules by vaporising them and passing them over a hot catalyst. Cracking is the process of converting alkanes into alkenes and shorter alkanes. We crack alkanes because the shorter chain alkanes are more valuable (they ... Nov 9, 2023 ... Both are thermal decomposition reactions. fractional distillation flow chart. The process of cracking produces both a shorter alkane and an ... Jan 4, 2025 ... The large hydrocarbon molecules are fed into a steel chamber, heated to a high temperature and then passed over an aluminium oxide (Al 2 O 3 ) catalyst.
