WebThe iodination of benzene is a reversible reaction. Therefore, yield of C 6 H 5 I is very poor because HI combines with C 6 H 5 I and forms back the reactants. In the presence of oxidizing agent like HIO 3 or HNO 3 , the co-product HI is oxidised to iodine and iodination proceeds favourably in the forward direction.
WebThe data above indicate that the halogen radicals have different reactivity; fluorine is the most reactive, and iodine is the least reactive. The iodine radical is very unreactive with overall “+” enthalpy, so iodine does not react with alkane at all. On the other side, the extreme high reactivity of fluorine is not a benefit either. WebThe iodination of benzene is a reversible reaction. Therefore, yield of C 6 H 5 I is very poor because HI combines with C 6 H 5 I and forms back the reactants. In the presence of …
WebBromo derivatives of alkanes are prepared by direct bromination. The reactivity order of abstraction of H atoms towards bromination of alkane is 3°H (tertiary) > 2°H (secondary) > 1°H (primary). Iodination and Fluorination. Direct iodination is not possible with iodine as the reaction is reversible.
