a student performed the following tests on an unknown substance A:
-Br2 dark and CHCl3 /AlCl3 tests were negative but Br2 light was positive and gave an acidic Litmus test
-the compound was partially water soluble and soluble in all organic solvents tested
-the product could not be extracted into alkaline water froman ether solution
-the test with 2,4-dinitrophenylhydrazine failed
-the lucas reagent gave a moderately fast reaction
-the CrO3 /H2SO4 test positive; but the product could not be extracted into alkaline water;
-the I2/ NaOH test was positive; after partitioning the product between water and ether the aqueous phase was acidified and extracted with fesh ether, and the ethe layer was distilled to give liquid with a strong vinegary smell boiling at the same boiling point as propanoic acid
-the sodiumtest produced copious amounts of the bubbling ( the gas was identified as H2 by flame test)
use these results to infer the structure of compound
