An organic compound contains `69.77%` carbon, `11.63%` hydrogen, and rest oxygen. The molecular mass of the compound is 86. It does not reduce Tollens reagent but forms an aditional compound with sodium hydrogensulphite and gives positive iodoform test. On vigorous oxidation, it gives ethanoic and propanoic acid. Write the possible structure of the compound.

Text Solution

Verified by Experts

The correct Answer is:
(i) For empirical formula
`{:("Element",%, "Relative no. of atoms","Simplest ratio"),(C,69.77,5.76,5),(H,11.63,11.63,10),(O,19.20,1.2,1):}`
`therefore` Empirical formula of compound is `C_(5)H_(10)O`.
and Empirical formula wt. =86
Also Molecular wt. =86
`therefore` Molecular formula of compound is `C_(5)H_(10)O`.
(ii) Compound form bisulphate addition compound and thus, has carbonyl group i.e., aldehyde or ketone.
(iii) It does not reduce Fehling solution and thus, it is not aldehyde but it is ketone.
(iv) It gives positive lodoform test and thus, it has
`(##ALN_CHM_C09(II)_E01_644_A01##)`
`CH_(3).CH_(2).CH_(2)underset(O)underset(||)C.CH_(3)` `(##ALN_CHM_C09(II)_E01_644_A02##)`
