Compound A treated with `NaNH_2` followed by `CH_3CH_2Br` gave compound B. Partial hydrogenation of compound B produced compound C, which on ozonolysis gave a carbonyl contpound D. `(C_3H_2O)`. Compound D did not respond to iodofom test with `I_2//KI` and NaOH. Find out the structures of A, B, C & D.

An organic compound E(C_5H_8) on hydrogenation gives compound F(C_5H_12) compound E on ozonolysis gives formaldehyde and 2-keto propanal deduce the structure of compound E

An organic compoud [A] which has characteristic odour on treatment with NaOH forms two compounds [B] and [C]. Compounds [B] has the molecule formula C_(7)H_(8)O . Which on oxidation gives back compound [A]-The compound [C] is the sodium salt of an acid [C]. When [C] is heated with sodalime, it yield an aromatic hydrocarbon [D]. Deduce the structures of [A], [B], [C] and [D].

An organic compound 'A' (C_(4)H_(10)O) is optically active. On mild oxidation, it gives a compound 'B' (C_(4)H_(8)O) but upon vigorous oxidation, it gives another compound 'C' (C_(3)H_(6)O_(2)) . The compound 'C' along with 'D' are also formed from 'B' by reacting with iodine in the presence of alkali. Deduce the structures of 'A', 'B', 'C' and 'D' .

Compound (A) C_(6)H_(12)O_(2) on reduction with LiAlH_(4) yields two compounds B and C. The compound (B) on oxidation gave (D) which on treatment with aqueous alkali and subsequent heating furnished E. The latter on catalytic hydrogenation gave (C). Compound (D) on oxidation gave monobasic acid (molecular formula weight = 60). Deduce the structure of (A), (B), (C), (D) and (E).
