An organic compound X with molecular formula C 6 H 10 , when treated with HBr , forms a gem dibromide. The compound X upon warming with HgSO 4 and dil. H 2 SO 4 , produces a ketone, which gives a positive iodoform test. The compound X is
Correct answer
3
Step-by-step solution
(Hydrobromination, Markownikoffs product, which is a gem-dibromide). Acid catalysed hydration of alkyne gives ketone. In the case of terminal alkyne, the product is a methyl ketone, which gives haloform test.
