Give the structures of A & B (explanation are not required)
(i) `A(C_4 H_8)` which adds on HBr in the presence and in the absence of peroxide to give same product.
(ii) `B(C_4 H_8)` which when treated with `H_2 O //H_2 SO_4` gives `C_4 H_(10)O` which cannot be resolved into optical

Give the structures of (A),(B) and (C)( explanation is not required ). i. (A)(C_(4)H_(8)) that adds on HBr in the presence and in the absence of peroxide to give the same product, C_(4)H_(9)Br . ii. (B)(C_(4)H_(8)), which when treated with H_(2)O //H_(2)SO_(4) gives C_(4)H_(10)O that cannot be resolves into optical isomers. iii. (C)(C_(6)H_(12), an optically active hydrocarbon which on catalytic hydrogenation gives an optically inactive compound, C_(6)H_(14))

H_(2)SO_(4) give C_(4)H_(10)O , which is non - resolvable. c. Give the structure of the alkane (C_(4)H_(8)) which adds HBr in the presence and absence of peroxide to give the same product C_(4)H_(9)Br. d. Arrange the following in the decreasing order of their reactivity towards alkenes : i. HCI,ii.HBr, iii. HI,iv. HF.

A substance C_(4)H_(10)O yields on oxidation a compound C_(4)H_(8)O which gives an oxime and a positive iodoform test. The original substance on treatment with conc. H_(2)SO_(4) gives C_(4)H_(8) , The structure of the compound is
