Question

in respect of boron trifluoride molecules (BF3) .Ans the following :
a)Number of line pair and bond pair electrons presents on central atom
b)hybridisation of the molecule
c)Name of its shape
​

Answer 1

Answer:

a-0 lone pair 3bond pair,

b-sp2

shape is t-shape

Explanation:

as valance cell electrones of boron are 3 it can form 3sigma bond and no lone pairs,

as 3sigma bond present 1s, 2p orbitals involved so hybridization sp2,and shape is t shape
