What is the molecular structure of BF3?
What is the molecular structure of BF3?
BF3 or boron trifluoride has a trigonal planar molecular geometry. BF3 has a central boron atom and three surrounding fluorine ligands. The three flourine atoms are positioned at the corners of a triangle, all in one three-dimensional plane. All three ligands are identical and have bond angles of 120 degrees.
Is BF3 a resonance structure?
Resonance Forms of BF3. BF3, whose structure is shown below on the left, is an example of an electron deficient compound. Note that the central boron atom is only surrounded by 6 valence electrons. The resonance structure shown on the right brings all atoms into compliance with the octect rule.
What is the molecular geometry of PF3?
The molecular geometry of PF3 is a trigonal pyramid and its electron geometry is tetrahedral because phosphorous has Sp³ hybridization with 5 valence electrons in its valence shell and it makes three bond pairs, one with each fluorine atom .
What is the shape of BF3?
Shape of NF3 is pyramidal while the shape of BF3 is triangular planar. There exists repulsion force between lone pair and bond pair of electrons in NF3 molecule because of which it acquires pyramidal shape. Where as in BF3 the central atom Boron undergoes SP2 hybridization and has no lone pair of electrons. Thus three Fluorine atoms will occupy three corners of triangular planar structure.
What is the molecular polarity of BF3?
The BF3 molecule has a symmetrical trigonal planar geometry, like the SO3 molecule. In such a structure, the resultant moment of any two B-F dipoles is equal in magnitude but opposite in direction to the moment of the third one. So, the net dipole moment of the BF3 molecule is zero, and it is non-polar.
What is the electron pair geometry of BF3?
The molecular geometry of BF3 is trigonal planar and it’s nonpolar. After hybridization (of Borons electrons), you get three equivalent sp2 orbitals at 120 degrees apart.
