Describe the shapes of BF(3) and BH(4)^(...

Describe the shapes of `BF_(3)` and `BH_(4)^(ө)`. Assign the hybridisation of boron in these species.

Text Solution

Verified by Experts

In `BF_(3),B` is `sp^(2)` hybridised, hence, `BF_(3)` has a planar geometry.
In `[BH_(4)]`,`B` is `sp^(3)` hybridised, hence, `[BH_(4)]^(ө)` has a tetrahedral geometry or shape.
