Boron triflouride behave as a lewis acid |
| Answer» The substance which can accept the electron pair donated by the Lewis base, they are termed as Lewis acid.\xa0is a compound which is made up of two atoms namely boron and fluorine.The atomic number of boron is 5 and its electronic setup is 2, 3. Its valency is 3 and Flourine (2,7) valency is 1.Consequently, by imparting 1 electron to every fluorine molecule, boron has 3 sigma bonds around it which means that each boron atom is surrounded by 6 electrons.To have the steady octet setup Boron needs 2 additional electrons.Since boron can accept a couple of electrons from Lewis base, it is considered as Lewis acid. | |
