InterviewSolution

1.	An organic compound decolorizes `Br_2` water and also gives red ppt. with `Cu_2Cl_2` solution the compound isA. `CH_2=CH_2`B. `CH_3CH=CH_2`C. `CH_3C-=CH`D. `CH_3C-=C CH_3`
Answer» Correct Answer - C All these compound are capable of decolorizing `Br_2` water as it is a test of unsaturation but only a terminal alkyne is capable of giving a red precipitate with `Cu_2Cl_2` on account of acidic H atom. `CH_3C-=CHoverset(Cu_2Cl_2)tounderset("Red ppt.")(CH_3C-=C C u(s))`
