Which of the following compounds has no covalent bonds? Na3PO4 KNO3 CH3I MgF2 HBrO3
Question
Which of the following compounds has no covalent bonds?
- Na3PO4
- KNO3
- CH3I
- MgF2
- HBrO3
Solution
The compounds without covalent bonds are Na3PO4 and MgF2. These are ionic compounds, not covalent. In ionic compounds, electrons are transferred from one atom to another, resulting in the formation of positive and negative ions. The electrostatic attraction between these ions forms the ionic bond.
On the other hand, covalent bonds are formed when two atoms share one or more pairs of electrons. The compounds KNO3, CH3I, and HBrO3 all contain covalent bonds because they are composed of nonmetals, which typically form covalent bonds with each other.
