Coordinate geometry lecture 2

Co ordinate geometry

When we study two dimensional coordinate geometry, then the set of all points in xy-plane is the universal set.

If D ,Ea n dF are the mid-points of sides BC, CA and AB respectively of a A B C , then using coordinate geometry prove that Area of △DEF= 1/4 (Area of △ABC)

Specify the coordination geometry around and the hybridisation of N and B atoms in 1 : 1 complex of BF_(3) and NH_(3) .

Specify the coordination geometry around and the hybridisation of N and B atoms in 1 : 1 complex of BF_(3) and NH_(3) .

A coordination complex has only two stereo isomers, having octahedral coordination geometry. Identify the complex(es) among the following: [Cr(H_(2)O_5 Cl]Cl_(2)]Cl_(2),[Cr(H_2O)_(3)Cl_(3)],[Ni(NH_3)_(4)Cl_(2)],[NH_4]_(2)[NiCl_6]

[NiCI_(2){P(C_(2)H_(5))_(2)(C_(6)H_(5))}_(2)] exhibits temperature dependent magnetic behaviour(paramagnetic//diamagnetic) The coordination geometries of Ni^(2+) in the paramagnetic and diamagnetic states are respectively .

The spin only magnetic moment of [MnBr_4]^(2-) is 5.9 B.M. Predict the geometry of the complex ion.
