Hydrogen only need 2 electrons to fulfill the outer shell. Boron is an exception just like aluminum where it can be octet deficient. Chemical Bonding and Molecular Structure 46 JEE - CHEMISTRY. National Institutes of Health. So, there are no lone pairs to mark on boron and hydrogen atoms. It should be noted that Hydrogen always go outside in lewis diagram Because, Hydrogen atom can form only one single bond. Consequently, it is a strong Lewis acid and reacts with any Lewis base ('L' in equation below) to form an adduct: in which the base donates its lone pair, forming a dative covalent bond. As the BH3 lewis structure has trigonal planar geometry or shape, so it has 120 degree bond angle. This means there are five electron pairs with a 175 F-Cl-F bond angle and a trigonal bipyramidal shape. Atoms and molecules are so small that we are unable to see them with our naked eyes. An interesting fact here is that each terminal H-atom has a complete duplet in BH3; however, the central B-atom only has a total of 6 valence electrons around it and thus an incomplete octet. It is an inflammable and toxic gas without any color. Boron has only three electrons in its last shell and all of them contribute to make three single bonds with three hydrogen atoms. The experimentally determined BH bond length is 119pm. In the case of the BH3 molecule, boron is the central atom that is attached to the three bonded atoms(hydrogen) and it has no lone pairs. - Polarity of Bromine trifluoride, Is SF2 Polar or Nonpolar?
