    During electrophilic substitution reaction of fullerene, the hybridisation of carbon atom

    A)  remains \[s{{p}^{2}}\] in reactant as well as product        

    B)  changes from \[{{\operatorname{sp}}^{2}}\,to s{{p}^{3}}\]

    C)  changes from \[s{{p}^{3}}\,to\text{ }s{{p}^{2}}\]

    D)  cannot be determined

    Correct Answer: B

    Solution :

    This problem includes concept of allotropic form of carbon (fullerene) and electrophilic substitution reaction of fullerene. When fullerene undergo electrophilic substitution, it undergo changes of hybridisation of carbon from\[{{\operatorname{sp}}^{2}}\,to s{{p}^{3}}\].
