Why are low spin tetrahedral complexes not formed ?

The crystal field splitting of tetrahedral complexes is more /less than octahedral complexes.

Explain the following : Low spin octahedral complexes of nickel are not known.

True of False : All tetrahedral complexes show geometrical isomerism.

Explain the following : Most of the tetrahedral complexes are high spin complexes.

An aqueous solution of metal ion M_1 reacts separately with reagents Q and R in excess to give tetrahedral and square planar complexes, respectively. An aqueous solution of another metal ion M_2 always forms tetrahedral complexes with these reagents. Aqueous solution of M_2 on reaction with reagent S gives white precipitate which dissolves in excess of S. The reactions are summarized in the scheme given below : M1, Q and R , respectively are :
