What type of bonds does BH3 have?

BH3 is a strange molecule since Boron doesn't have an octet rule, but rather a sexet rule meaning 6 valence electrons as opposed to 8 for it's valence shell. BH3 is a metal, Boron, and three nonmetals, Hydrogen, so it is an ionic bond.


What type of bonds does BH3 have via electronnegativity difference?

BH3 does not exhibit typical covalent or ionic bonds due to the lack of electrons in boron's valence shell. Instead, BH3 forms coordinate covalent bonds where a shared pair of electrons come from a donor atom with a lone pair.

How many bonds should be drawn in the Lewis-dot structure for BH3?

In the Lewis dot structure for BH3, there should be 3 bonds drawn. Each hydrogen atom forms a single covalent bond with the boron atom. Boron has three valence electrons, so it can form three bonds with the hydrogen atoms.
