nonpolar covalent
CO2 has a polar covalent bond because there is a significant difference in electronegativity between carbon and oxygen, causing a partial negative charge on oxygen atoms and a partial positive charge on the carbon atom.
Polar covalent. The difference in electronegtivity is insufficient for an ionic bond
H2O is a polar covalent molecule. It forms covalent bonds between the hydrogen and oxygen atoms, but due to the unequal sharing of electrons, the oxygen atom becomes slightly negative while the hydrogen atoms become slightly positive, leading to a polar molecule.
Covalent- the small difference in electronegativity is the reason.
Hydrogen bonds are the weakest of the listed chemical bonds. They result from the attraction between a hydrogen atom covalently bonded to an electronegative atom (e.g., oxygen, nitrogen, or fluorine) and another electronegative atom. Ionic bonds, polar covalent bonds, and non-polar covalent bonds are stronger than hydrogen bonds.

Sodium bicarbonate is an ionic compound.
Magnesium chloride has an ionic bond.
Br2 is non polar covalent
CO2 has a polar covalent bond because there is a significant difference in electronegativity between carbon and oxygen, causing a partial negative charge on oxygen atoms and a partial positive charge on the carbon atom.
The F-F bond (in F2) is covalent, and non polar covalent at that.

It is a non-polar covalent bond. O - C - O The oxygen atoms have a delta- charge, and the carbon a delta+ charge. Because the negative charges pull the electron cloud into different directions, it has no side which is more electronegative than the other. Therefore it is a non-polar covalent bond.
