Question
What type of bond exists between hydrogen and fluorine?
Solution
The bond between hydrogen and fluorine in a molecule of hydrogen fluoride (HF) is a polar covalent bond.
Here's why:
-
Covalent bonds form when two atoms share electrons. Both hydrogen and fluorine share a pair of electrons in HF.
-
However, fluorine is more electronegative than hydrogen. This means fluorine has a stronger pull on the shared electrons, causing a charge separation with a partial negative charge on fluorine and a partial positive charge on hydrogen.
-
This charge separation makes the bond polar, hence the term "polar covalent bond".
