    Consider the following reaction                  [AIPMT (S) 2009]
    \[\underset{\begin{smallmatrix}  \text{ }\!\!|\!\!\text{ } \\  \text{CHO} \end{smallmatrix}}{\mathop{\text{CHO}}}\,\]\[1.5\times {{10}^{-s}}\]the product Z is

    A) \[4.5\times {{10}^{-10}},\]       

    B) \[C{{N}^{-}}+C{{H}_{3}}COOH\]

    C) \[HCN+C{{H}_{3}}CO{{O}^{-}}\]

    D) \[3.0\times {{10}^{5}}\]

    Correct Answer: D

    Solution :

    [d] Key Idea (i) \[e=\frac{-d\phi }{dt}=\frac{-BdA}{dt}=-B\frac{d(\pi {{r}^{2}})}{dt}\]is a halogenating agent, ie, converts —OH group into —Br.
    (ii) Ale. KOH is a dehydrohalogenating agent.
    (iii)\[=-B\pi 2r\frac{dr}{dt}\] and \[e=-0.04\times \pi \times 2\times 2\times {{10}^{-2}}\times 2\times {{10}^{-3}}\]converts an olefin into alcohol.
    \[=3.2\pi \mu V\]\[=[{{M}^{0}}{{L}^{1}}{{T}^{-1}}]\]\[=[{{M}^{0}}{{L}^{1}}{{T}^{-2}}]\]
