Question

page 9 of 10 question 9 which is an example of a molecule that has polar covalent bonds? a salt b phosphorus c carbon dioxide d methane e water

Explanation:

Polar covalent bonds occur when there is an unequal sharing of electrons between atoms due to differences in electronegativity. In water ($H_2O$), oxygen is more electronegative than hydrogen, leading to polar covalent bonds. Salt has ionic bonds, phosphorus is a single - element substance without covalent bonds in the context of this question, carbon dioxide has polar bonds but is a non - polar molecule overall due to its linear shape, and methane has non - polar covalent bonds as the electronegativity difference between carbon and hydrogen is small.

Answer:

E. water
