    Expert Answer

    Answer:

    Consider the forthcoming chemical reactions (none of which you feel to perceive at this object). In each fact content fulfill the professional collection of the asterisked () carbon in twain the starting symbolical and issue its the identical C in twain). Then detail that carbons oxidation smooth, and mark on the just whether there has been a enmesh oxidation (IOl), diminution (HI) or no alter (dispersion your dainty). Understand that the equations repudiate unmistakable other mark, and so show to be unbalanced 01? HI 2 no alter? 2.5 equiv.

    Answer:

    (a) The professional collections of the asterisked carbon in twain the starting symbolical and issue are lactam (cyclic amide) and secondary amine, respectively.

    The oxidation smooths of the asterisked carbon in twain the starting symbolical and issue are +2 and -2, respectively.

    Explanation: x + 1 – 2 – 1 = 0, i.e. x = +2 and x + 1 + (2*1) – 1 = 0, i.e. x = -2

    i.e. There is a enmesh diminution ( [H] ).

    (b) The professional collections of the asterisked carbon in twain the starting symbolical and issue are ketal (bis ether steadfast to ketonic carbon) and ketone, respectively.

    The oxidation smooths of the asterisked carbon in twain the starting symbolical and issue are 0 and 0, respectively.

    Explanation: x + 1 – 1 – 1 + 1 = 0, i.e. x = 0 and x + 1 – 2 + 1 = 0, i.e. x = 0

    i.e. There is a no enmesh alter.

    (c) The professional collections of the asterisked carbon in twain the starting symbolical and issue are acetal (bis ether steadfast to aldehydic carbon) and ester, respectively.

    The oxidation smooths of the asterisked carbon in twain the starting symbolical and issue are 0 and 0, respectively.

    Explanation: x + 1 – 1 – 1 + 1 = 0, i.e. x = 0 and x + 1 – 2 – 1 = 0, i.e. x = +2

    i.e. There is a enmesh oxidation ( [O] )
