An organic compound 'A' having molecular formula `C_(6)H_(6)O` gives a characteristic colour with aqueous `FeCl_(3)` solution. When 'A' is treated with `CO_(2)` and NaOH at 400K under pressure. 'B' is obtained. B on acidification gives C when C treated with `CH_(3)COCl` gives a popular pain killer D. Deduce the strucutrues of A,B,C and D.

`{:("Atomic weight",,"Atomic ratio"),(C=76.6,=76.6//12,=6.38~~6),(H=6.38,=6.38//1,=6.38~~6):}`
`O=100-(76.6+6.38)=17.02//16=1.06~~1`
Emperical formula `=C_(6)H_(6)O`
Emperical formula weight=94
Molecular weight=`V.d.xx2=47xx2=94`
So, molecular formula=`C_(6)H_(6)O`
Since (A) gives characteristic colour with aqueous `FeCl_(3)`. So it must be a phenolic compound and the formula of (A) may be
