How is a polar covalent bond different between from a covalent bond?

Answer 1

Covalent compounds are neutral. When a covalent compound is polar, like H2O, it means that H have a slightly positive charge while O has a slightly negative charge, hence the charges are shared unequally.

Answer 2

If the electronegativities of the two atoms in the bond are exactly equal or very close to equal, then the bond is non-polar covalent. This is always the case if the two atoms bonded are identical to each other, but sometimes two atoms have very similar electronegativities to each other, resulting in a non-polar bond.

If the electronegativities are similar, but not equal, then the bond is polar covalent (if the difference is greater than 0.3 but less than 1.7)

If the electronegativities are very different, then the bond is ionic (if the difference is greater than 1.7).

the electronegativity can be found using number of scales and many scientists were worked on it. the highly recognised scales were pauling's scale and mulliken's scale.

Answer 3

A polar covalent bond is when one atom holds one or more of the sharing electrons closer to itself ie. the electrons spend a longer time around some atom/s than the other/s. A covalent bond occurs when 2 or more electrons share valence electrons in order to achieve stability.
A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms. The stable balance of attractive and repulsive forces between atoms when they share electrons is known as covalent bonding.

Answer 4

A covalent bond is formed by sharing of electrons between two atoms of nearly same electronegativity.

When the shared pair of electrons are equally distributed between the two atoms the bond is nonpolar. It happens when atoms are of same element.

When the shared pair of electrons are more closer to one atom then the bond is polar. It happens between atoms of slightly different electronegativity.

Answer 5

While both have covalent bonds rather than ionic bonds, the covalent molecule can still be polar when it's charges are not distributed evenly/symmetrically along the molecule. Their charges do not come from the anions and cations which lose or gain electrons in ionic bonding, but rather from the covalent sharing of electrons, in which case one or more atoms in the molecule often is stronger or weaker leading to an unfair sharing of the electron pair in the covalent bond. Additionally unpaired electrons can cause a rather powerful negative cloud of charge covering a particular region of the molecule. Nitrogen in amino groups does this a lot, and oxygen bound such as in ketones "hog" their shared electrons again leading to negative areas on the molecule. These type of forces are primarily responsible for the polar covalent type of situation. While a nonpolar molecule shares more nicely, like plain hydrocarbon chains (butane, n-heptane, n-hexane, etc.)

Answer 6

A polar covalent bond is not different from a covalent bond, because a polar covalent bond is a covalent bond. Polar covalent bonds are a category of covalent bonds which are distinguished from other covalent bonds by larger bond dipole moments, caused by a greater average electron density near the more electronegative element that is so bonded.

Answer 7

Nonpolar covalent bonds are a type of chemical bond where two atoms share a pair of electrons with each other. Polar covalent bonding is a type of chemical bond where a pair of electrons is unequally shared between two atoms.

Answer 8

polar bonds are non metals bonded to non metals and non polar covalent bonds are bonds sharing electrons.....
