Then, what is the shape of the boron trifluoride molecule?
Boron trifluoride only has six valence electrons and is one of the relatively rare second period covalent molecules that disobeys the octet rule. There are three bonded groups and so no lone pairs. Six electrons implies three electron pairs and therefore a trigonal geometry.
What is the structure of bf3?
A step-by-step explanation of how to draw the BF3 Lewis Dot Structure (Boron Trifluoride). For the BF3 Lewis structure, calculate the total number of valence electrons for the BF3 molecule. After determining how many valence electrons there are in BF3, place them around the central atom to complete the octets.
What is the shape of bf3 according to Vsepr theory?
Repulsion between these electrons can be minimized by arranging them toward the corners of an equilateral triangle. The VSEPR theory therefore predicts a trigonal planar geometry for the BF3 molecule, with a F-B-F bond angle of 120o.
