Compound (X)`C_9H_10O` is inert to `Br_2//C Cl_4`.Vigorous oxidation with hot alkaline `KMnO_4//OH` yield `C_6H_5COOH` (X) gives precipitate with 2,4-Dintrophenyl hydrazine. How can these isomers be distinguished by the usual chemical tests ? Following are possible isomers of X : (i)`C_6H_5-CH_2-CH_2-CHO` , (ii)`C_6H_5-undersetunderset(CH_3)(|)CH-CHO` (iii)`C_6H_5-CH_2-oversetoverset(O)(||)C-CH_3` , (iv)`C_6H_5-oversetoverset(O)(||)C-CH_2-CH_3`A. I gives red ppt. with Fehling solution and II & III can be distinguished by iodoform testB. I & II can be distinguished by simple chemical methodC. I & II give red ppt. with Fehling solution and III & IV can be distinguished by iodoform testD. II gives red ppt. with Fehling solution and I & IV can be distinguished by iodoform test |
