    Which of the following is incorrect?

    A)  Among diamond, graphite and silica, diamond shows moderate electrical conductivity.

    B)  N-O bond length is more in NO than \[N{{O}^{+}}\].

    C)  Bonding molecular orbitals are formed by the constructive interference of electron waves.

    D)  Ge(II) compounds are powerful reducing agents whereas Pb(IV) compounds are strong oxidants

    Correct Answer: A

    Solution :

    Graphite shows moderate electrical conductivity on account of TC-electrons. Ge(II) compounds are powerful reducing agents whereas Pb(IV) compounds are strong oxidants. It can be due more pronounced inert pair effect in lead than in Ge.
