    Geometry of reaction intermediate in\[{{S}_{N}}1\]reaction is

    A)  tetrahedral

    B)  planar

    C)  triangular bipyramidal

    D)  None of the above

    Correct Answer: B

    Solution :

     \[{{S}_{N}}1\]reaction is a two step reaction. In the first step of the reaction intermediate carbocation is formed which is in\[s{{p}^{2}}\]hybridised state, hence the geometry of the reaction intermediate is planar.
