Vedclass · Answer

(A) The molecular weight of the compound is calculated as $2 	imes 	ext{Vapour density} = 2 	imes 29 = 58$. The molecular weights of the given compounds are: $CH_3CH_2CHO = 58$ $CH_3CHOHCH_3 = 60$ $CH_3COCH_3 = 58$ $CH_3CH_2COOH = 74$ Both $CH_3CH_2CHO$ and $CH_3COCH_3$ have a molecular weight of $58$. The iodoform test (yellow precipitate with alkali and iodine) is given by compounds containing the $CH_3CO-$ group or $CH_3CH(OH)-$ group. Among the options,$CH_3COCH_3$ (acetone) contains the $CH_3CO-$ group and gives a yellow precipitate of iodoform. $CH_3CH_2CHO$ does not give this test.

$A$ compound has a vapour density of $29$. On warming with an aqueous solution of alkali,it gives a yellow precipitate. The compound is
