Correct Answer: A
Solution :
: Benzene can be prepared by cyclisation of long chain alkanes on heating at \[500-550{}^\circ C\] under high pressure in presence of catalyst \[Cr{{O}_{3}}\]supported on alumina or \[Pt-A{{l}_{2}}{{O}_{3}}\](i.e., catalytic reforming). \[\underset{n-hexane}{\mathop{{{C}_{6}}{{H}_{14}}}}\,\underset{at\,high\,pressure}{\mathop{\xrightarrow[773K]{Cr{{O}_{3}}/A{{l}_{2}}{{O}_{3}}}}}\,\underset{(A)}{\mathop{{{C}_{6}}{{H}_{6}}}}\,+4{{H}_{2}}\]You need to login to perform this action.
