A polar molecule is similar to a magnet, it has a positively charged side and a negatively charged side on the opposite side. When polar molecules are near each other, their positive sides are attracted to each other's negative sides, and vice-versa. This attraction is called a hydrogen bond.
Hydrogen bonds are weak, but they are strong enough to form water drops and puddles and to keep the 2 strands of a DNA molecule together.

∙ 9y agoA polar molecule forms there is a highly electronegative atom that bonds with less electronegative atoms. A net negative charge will gather on the electronegative atom, leaving a net positive charge on the opposite side of the molecule.

∙ 14y agoA polar covalent bond is formed when 2 atoms are sharing the same electron unequally.
It occurs because one of the atoms has a stronger affinity for electrons that the other.

∙ 9y agoPolar bonds potentially make a molecule polar. However if the molecule has symmetry that allows the bond moments to cancel out, as in CCl4 which is non-polar.

They form when the electronegativy difference between the anion and cation is between 0.4 and 1.7.

What type of covalent bond form in a water molecule?
Polar covalent bond
What type of bond forms between 2 iodine atoms?
An ionic bond - sodium and iodine form NaI, containing Na+ and I- ions.
Will N and F form a covalent bond?
Yes, they form a polar covalent bond e.g. in NF3
When is a covalent bond most likely to be polar?
A covalent bond is most likely to be polar when there is a large difference in the electronegativity of the two atoms that form the bond.
Do O and O form polar covalent bonds?
No, the bond is covalent, but as the atoms are identical, it is non-polar.

Will N and F form a covalent bond?
Yes, they form a polar covalent bond e.g. in NF3
When is a covalent bond most likely to be polar?
A covalent bond is most likely to be polar when there is a large difference in the electronegativity of the two atoms that form the bond.
Do O and O form polar covalent bonds?
No, the bond is covalent, but as the atoms are identical, it is non-polar.
Would H and S perform a polar covalent bond?
Yes. Sulfur (S) and hydrogen (H) will form a polar covalent bond.
Would N and F form a polar covalent bond?
The electronegativities of nitrogen and fluorine are considerably different. Therefore they make a polar covalent bond.
Would Na and F form a polar covalent bond?
No, they would form an ionic bond.
What type of bond is between C and O?
A molecule of carbon monoxide has polar covalent bonds.
What happens when a polar covalent bond and a nonpolar covalent substance combine?
a bond of some type will form haha
What element is a polar covalent bond?
No single element can form a bond. Only 2 or more elements can form bonds. Polar bonds occur when there is a dipole moment, or there is asymmetry in the structure. For example, HF forms a polar covalent bond.
What type of bond does Cl and F have?
The bond between F and Cl is a polar covalent bond. Fluorine is very electronegative and Cl is not as much. The difference is large enough to be considered polar.
