    Which is correct order of stability for the following intermediates?

    A)  \[{{(C{{H}_{3}})}_{3}}\overset{\oplus }{\mathop{C}}\,<Ph-\overset{\oplus }{\mathop{C}}\,{{H}_{2}}\]

    B)  \[{{(C{{H}_{3}})}_{3}}\overset{\oplus }{\mathop{C}}\,>Ph\,\,\overset{\oplus }{\mathop{C}}\,{{H}_{2}}\]

    C)  \[\overset{-}{\mathop{C}}\,{{H}_{3}}<{{(C{{H}_{3}})}_{3}}{{C}^{-}}\]

    D)  

    Correct Answer: B

    Solution :

    \[{{(C{{H}_{3}})}_{3}}\overset{\oplus }{\mathop{C}}\,\] is more stable than Ph \[Ph\overset{\oplus }{\mathop{C}}\,{{H}_{2}}\].
