Water has a polar covalent bond because the electrons that the hydrogens share with the oxygen hang out around the oxygen more than the hydrogens. This is because the oxygen has more protons in its nucleus than the hydrogen. The hydrogen become positively charged and the oxygen becomes negatively charged. Then also when the molecule becomes cold, loses energy, the hydrogens get closer to each other, but they repel each other, which is why ice is less dense than water. The hydrogen then also forms hydrogen bonds with the other water molecules, attaching to the negatively charged oxygens.
What else can I help you with?
The bonds between hydrogen and oxygen in a water molecule are classified as?
The bonds between hydrogen and oxygen in a water molecule are classified as polar covalent bonds. In a polar covalent bond, electrons are shared between the atoms but are not shared equally, leading to a partial negative charge near the oxygen atom and a partial positive charge near the hydrogen atoms.
Are all compounds with polar covalent bonds are polar molecules?
No, not all compounds with polar covalent bonds are polar molecules. Whether a molecule is polar or nonpolar depends on its overall symmetry and the arrangement of its polar bonds within the molecule. In some cases, the polarities of individual bonds may cancel out, resulting in a nonpolar molecule.
Why is it important to understand why covalent bonds are polar?
Understanding why covalent bonds are polar is important because it helps explain how molecules interact with each other. Polar covalent bonds result in unequal sharing of electrons, leading to partial positive and negative charges within a molecule. This affects the molecule's overall shape, properties, and interactions with other molecules, which is crucial in fields such as chemistry, biology, and materials science.
Are molecules with two polar covalent bonds always polar molecules?
Not necessarily. A molecule with two polar covalent bonds may or may not be polar, depending on the overall molecular geometry and symmetry. If the polar bonds are symmetrically arranged and cancel each other out, the molecule could be nonpolar.
Which substance has polar covalent bonds SO2 Cl2 N2 or CaO?
SO2 is the substance that has polar covalent bonds. This is because sulfur and oxygen have different electronegativities, resulting in an uneven sharing of electrons in the covalent bonds within the molecule.
What types of bonds hold together a water molecule?
Water has covalent bonds.The bonds between atoms in a water molecule are covalent bond, somewhat polar ones.
A molecule in which the polar covalent bonds do not cancel out?
unsymmetrical
Is HCN nonpolar covalent bond?
This molecule contains polar covalent bonds.

Name a non-polar covalent molecule having polar bonds?
carbon dioxide

Will A molecule with polar covalent bonds will definitely be a polar molecule?
not necessarily. if the individual dipoles cancel off, then the molecule will be non-polar. As in CCl4, PCl5 etc
how do you explain what polar molecules are?
Water molecules are polar molecules. Both of the bonds inside the molecule are polar bonds.
Which substance has polar covalent bonds SO2 Cl2 N2 or CaO?
SO2 is the substance that has polar covalent bonds. This is because sulfur and oxygen have different electronegativities, resulting in an uneven sharing of electrons in the covalent bonds within the molecule.
Is Fe2O3 polar or nonpolar?
Fe2O3 (iron oxide) is a nonpolar molecule because it has a symmetrical arrangement of its polar covalent bonds. The dipole moments in these bonds cancel each other out, resulting in a nonpolar overall molecule.
