Question

A student performed the following tests on an unknown substance A:
%u2022Br2/dark and CHCl3/AlCl3 tests were negative but Br2/light was positive and gave an acidic Litmus test;
%u2022the compound was partially water-soluble and soluble in all organic solvents tested;
%u2022the product could not be extracted into alkaline water from an ether solution;
%u2022the test with 2,4-dinitrophenylhydrazine failed; %u2022the Lucas reagent gave a moderately fast reaction;
%u2022the C rO3/H2SO4 test was positive, but the product could not be extracted into alkaline water; %u2022the I 2/NaOH test was positive; after partitioning the product between water and ether, the aqueous phase was acidified and extracted with fresh ether, and the ether layer was distilled to give a liquid with a strong vinagry smell boiling at the same boiling point as propanoic acid;
%u2022the sodium test produced copious amounts of bubbling (the gas was identified as H2 by a flame test). Use these results to infer the structure of compound A
