The reaction of benzene over $\ce{V2O5/ PtAu}$ catalyst at lower temperatures, can convert benzene to phenol with some success. See this book here Direct hydroxylation of benzene [The original question before editing was: What is the Ratta Maar Reaction?] Someone has played a prank with you with the named reaction. "Ratta maar" is a slang for "rote ...

The terminology given to that reaction by your instructors is very odd. But the more important thing is that $\ce{V_2O_5}$ isn't a reagent in converting benzene directly to phenol, rather it is a catalyst. The first few pages of the book linked by @M.Farooq writes [...] Various sources have reported the use of nitrous oxide to supply the active oxygen [...

Thank you for the question. This is a very basic physical chemistry question but the way it has been asked is interesting. In order to understand the probability of displacement of a H from any X-H bond (X is any atom), you need to know its pKa. The pKa values are as follows (ref.): pKa of water = 14 pKa of OH (phenol) = 9.95 pKa of CH (benzene) = 43 If ...
