It's a 4 marker asking 'explain why a BF3 molecule has the shape you have drawn' Please help Probably marks for saying.-> 3 bonded pairs-> no lone pairs -> lone pairs repel more strongly than bonded pairs.-> repel each other equally at 120 degrees -> the molecules are all aligned in one plane - essentially, the molecule is flat. ... What is the total number of electron domains for a molecule having a T-shaped pyramidal molecular geometry such as BrF3? The two possible geometries are trigonal pyramidal and t-shaped. 5. It’s like peripheral atoms all in one plane, as all three of them are similar with the 120° bond angles on each that makes them an equilateral triangle. The reason it is trigonal pyramid and not planar is because of the repulsion of the electrons of the central atom (Br) to the individual Br - F bonds, which sort of "close' them, make them bend and became the edges of the pyramid (check the VSEPR theory). The nitrogen in ammonia has 5 valence electrons and bonds with three hydrogen atoms to complete the octet.This would result in the geometry of a regular tetrahedron with each bond angle equal to cos −1 (− 1 / 3) ≈ 109.5°.
