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

    Statement-1: All tetrahedral complexes are mainly high spin and the low spin configurations are rarely observed. Statement-2: Delta_(t) is always much smaller even with stronger field ligands and it is never energetically favourable to pair up the electrons.
