The geometry of paramagnetic nickel complex [NiCl₄]²⁻ is:
d⸠paramagnetic prefers tetrahedral.
tetrahedral
octahedral
square planar
distorted octahedral
Ni²⁺ in [NiCl₄]²⁻ is 3d⁸ and paramagnetic, hence adopts tetrahedral geometry. Square planar is typical for diamagnetic d⁸ complexes.
The steam volatile compounds among the following are:

The structure of the major product formed in the following reaction is:


Draw a rough sketch for the curve $y = 2 + |x + 1|$. Using integration, find the area of the region bounded by the curve $y = 2 + |x + 1|$, $x = -4$, $x = 3$, and $y = 0$.
