Hello ,

The shape of BF3 is bent T shaped and it can be explained using VSEPR theory as shown below :

  • The central atom Br has seven electrons in valence shell
  • There are three bond pairs and two lone pairs
  • According to VSEPR theory, these will occupy the corners of trigonal bipyramid
  • The two lone pairs will occupy the equitorial positions to minimize lone pair-lone pair repulsions which is greater the bp-bp repulsions
  • The axial fluorine atoms will be bent towards the equitorial fluorine in order to minimize repulson .

Hope This Helps .
