`underset((aq))Co^(2+)+underset((aq))SCN^(-)to` complex (a)
`underset((aq))Ni^(2+)+dmgoverset(NH4OH)to` complex (y)
The CN of Co, Ni in comp,exes (x) & (y) are four
The geometry of complex (x) & (y) are respectively

A

Tetrahedral & square planar

B

both tetrahedral

C

Square planar, tetrahedral

D

both square planar

Text Solution

Verified by Experts

The correct Answer is:
B
`X=[Co(SCN)_(4)]^(2-)`
`Y=[Ni(dmg)_(2)]`
Both of them axetetrahedral and `sp^(3)` hybridised.
