Is the bond between b and h in bh4- polar covalent?
1 answer
The bond between B and H in BH4- is considered polar covalent. In this molecule, boron (B) is more electronegative than hydrogen (H), causing a partial negative charge on the hydrogen atoms and a partial positive charge on the boron atom. This polarity results in B attracting more electron density towards itself, leading to a polar covalent bond.
