Describe the shapes of and . Assign the hybridisation of boron in these species

(I)

Boron will in general shape monomeric covalent halides in view of its little size and high electronegativity. These halides of boron generally have a planar three-sided calculation, which can be clarified by the cross-over of three hybridized orbitals of boron with the sp orbitals of 3 halogen particles. It very well may be noticed that boron is hybridized in .

 

(ii)

– has a tetrahedral structure which is represented by the hybridized orbitals.
