The electron structure of ammonia (NH3) consists of two electrons in the 1s orbital, two in the 2s orbital, and three in the 2p orbital for a total of five valence electrons. Boron trifluoride (BF3) contains three valence electrons in the 2s and 2p orbitals of the boron atom, and three bonding pairs from the fluorine atoms.

How is the structure of boron trifluoride?
Boron trifluoride has a trigonal planar structure, with the boron atom at the center and three fluorine atoms surrounding it in a flat, triangular arrangement. The molecule has a total of four electron pairs around the boron atom, including three bonding pairs and one lone pair.
Why boron trifluoride have maximum covalency is 4?
Boron trifluoride has a maximum covalency of 4 because boron has three valence electrons and each fluorine atom contributes one electron. This allows boron to form four covalent bonds by sharing its three electrons with three fluorine atoms and the fourth electron from one of the fluorine atoms. This results in a stable structure with each atom having a full outer electron shell.
Chemical name of NH3?
Ammonium Boron Trifluoride.
What is the intermolecular force of boron trifluoride?
The intermolecular force in boron trifluoride is London dispersion forces. These forces occur due to temporary fluctuations in electron distribution, leading to the formation of temporary dipoles.
Boron trifluoride has 3 bonding domains and its electron domain geometry is trigonal planar?
Correct. Boron trifluoride has three bonding domains, which results in a trigonal planar electron domain geometry. The molecule has a central boron atom surrounded by three fluorine atoms, with a total of 6 valence electrons.

6 Write a chemical equation showing the reaction between ammonia and boron trifluoride BF3 in a Lewis acid-base reaction Show how the covalent bond forms?
The reaction between ammonia and boron trifluoride, BF3If you have recently read the page on covalent bonding, you may remember boron trifluoride as a compound which doesn't have a noble gas structure around the boron atom. The boron only has 3 pairs of electrons in its bonding level, whereas there would be room for 4 pairs. BF3 is described as being electron deficient.The lone pair on the nitrogen of an ammonia molecule can be used to overcome that deficiency, and a compound is formed involving a co-ordinate bond.Using lines to represent the bonds, this could be drawn more simply as:The second diagram shows another way that you might find co-ordinate bonds drawn. The nitrogen end of the bond has become positive because the electron pair has moved away from the nitrogen towards the boron - which has therefore become negative. We shan't use this method again - it's more confusing than just using an arrow.

Bond type of boron trifluoride?
Boron trifluoride (BF3) is a covalent compound. It forms covalent bonds between the boron atom and each of the fluorine atoms by sharing electrons. The fluorine atoms each contribute one electron to the bond, resulting in a stable structure.
What is the chemical formula for boron trifluoride?
The chemical formula for boron trifluoride is BF3.
Is boron trifluoride polar?
Yes, boron trifluoride is polar because of the difference in electronegativity between boron and fluorine atoms. The fluorine atoms impart a partial negative charge, while the boron atom carries a partial positive charge, creating an uneven distribution of electron density.
