  • The tetrahedral complexes are

    A
    `Ni(CO)_(4)`
    B
    `[FeCl_(4)]^(-1)`
    C
    `[MnCl_(4)]^(2-)`
    D
    `[CoCl_(4)]^(2-)`

  • Nearly all tetrahedral complexes are

    A
    high spin
    B
    low spin
    C
    intermediate spin
    D
    complex spin

  • Tetrahedral complexes are generally favoured :

    A
    where the ligands are bulky
    B
    when the ligands are stronger
    C
    where the electronic configuration of the central metal is `d^(0)d^(5)" or "d^(10)` (with weak field ligands) as there is no CSFE.
    D
    when the central metal ion has pseudo noble gas electron configuration, i.e.`(n-1)d^(10)ns^(0)np^(0).

    Tetrahedral complexes are generally favoured :

    Assertion (A) : Low spin tetrahedral complexes are rarely observed. Reason (R) : Crystal field splitting is less than pairing energy for tetrahedral complexes.

    Assertion (A): Low spin tetrahedral complexes are rarely observed. Reason (R ): Crystal field splitting energy is less than pairing energy for tetrahedral complexes.

    Assertion (A) : Low spin tetrahedral complexes are rarely observed. Reason (R ) : The orbital splitting energies are not sufficiently large to forcing pairing
