Oxygen attracts electrons more strongly than hydrogen does. What kind of bond forms between the two hydrogen atoms and single oxygen atom that form a water molecule?
A. A metallic bond
B. A hydrogen bond
C. An ionic bond
D. A polar bond
Currently stuck here.
D polar bond.
metallic bond forms between metals
hydrogen bond forms between hydrogens
an ionic bond would form in something like NaCl.
polar bond is where they share electrons unevenly.
covalent bond is when they share electrons equally.
The correct answer is D. A polar bond.
In a water molecule (H2O), each hydrogen atom shares its single electron with the oxygen atom. Oxygen has a greater electronegativity (ability to attract electrons) compared to hydrogen. As a result, the oxygen atom attracts the shared electrons more strongly, leading to an uneven distribution of electron density in the molecule. This results in a partial negative charge on the oxygen atom and partial positive charges on the hydrogen atoms.
The difference in electronegativity between hydrogen and oxygen is significant enough to create a polar bond, where electrons are not shared equally between the atoms. Therefore, option D, a polar bond, is the correct answer.
To determine the type of bond that forms between the two hydrogen atoms and a single oxygen atom in a water molecule, we need to compare the electronegativities of the elements involved.
Electronegativity is the tendency of an atom to attract electrons towards itself in a chemical bond. The greater the difference in electronegativity between two atoms, the more polar the bond will be.
In this case, oxygen (O) has a higher electronegativity than hydrogen (H). Oxygen attracts electrons more strongly than hydrogen does. As a result, the shared electrons in the water molecule spend more time around the oxygen atom, creating a partial negative charge (δ-) on the oxygen and partial positive charges (δ+) on the hydrogen atoms.
Based on this information, the kind of bond that forms between the two hydrogen atoms and the single oxygen atom in a water molecule is a polar bond.
Thus, the correct answer is:
D. A polar bond
