An organic compound containing C, H and O gives following observations:
(i) It exists in two isomeric forms (A) and (B).
(ii) 0.108 g of one of the isomers on combustion gave 0.308 g of `CO_(2)` and 0.072 g of `H_(2)O`
(ii) 0.108 g of one of the isomers on combustion gave 0.308 g of `CO_(2)` and 0.072 g of `H_(2)O`
(iii) (A) is insoluble in NaOH and `NaHCO_(3)` while (B) is soluble in NaOH.
(iv) (A) reacts with Hl to give compound (C ) and (D). (C ) can be separated from (D) by ethanolic `AgNO_(3)` solution and (D) is soluble in NaOH.
(v) (B) readily reacts with bromine water to give compound (E) of molecular formula `C_(7)H_(5)OBr_(3)`
The empirical formula of (A) and (B) is

Options
