    Consider the following carbocations.
    [a] \[CI_{3}^{+}C\]                
    [b] \[C{{I}_{2}}\overset{+}{\mathop{C}}\,H\]
    [c] \[CICH_{2}^{+}\]              
    [d] \[\overset{+}{\mathop{C}}\,{{H}_{3}}\]
    The stability sequence follows:

    A) iv < i < ii < iii 

    B) i < ii < iii < iv

    C) iv < i < iii < ii

    D) iv < ii < i < iii

    Correct Answer: B

    Solution :

    [b] i < ii < iii < iv Carbcation: Chemical species bearing a +ve charge on carbon and carrying sixe electrons in its valence shell are called carbocation. Order of stability: \[{{3}^{{}^\circ }}>{{2}^{{}^\circ }}>{{1}^{{}^\circ }}\]
