Q1 / 160 · WBJEE 2011 · Chemistry

Two aromatic compounds having formula \(\mathrm{C}_7 \mathrm{H}_8 \mathrm{O}\) which are easily identifiable by \(\mathrm{FeCl}_3\) solution test (violet colouration) are

  • Correct answer
    A
    o- cresol and benzyl alcohol
  • B
    m-cresol and p-cresol
  • C
    o-cresol and p-cresol
  • D
    methyl phenyl ether and benzyl alcohol

Solution

Hints: \(\mathrm{O}\) - cresol contains phenolic group, thus it gives violet coloration with \(\mathrm{FeCl}_3\) where as benzylalchol donot contains phenolic group, hence no coloration with \(\mathrm{FeCl}_3\). Hence Identifiable

Hence, the correct answer is option: 'A'.
