Comparing Polar Bonds & Polar Covalent Bonds

[sophipie27]

how are polar bonds formed?

are polar bonds and polar covalent bonds the same thing?

polar bonds are formed by a partial charge (i.e H20) and they are not the same as a covalent bond.

well there are polar covalent bonds

there are polar and non-polar covalent bonds. if the difference between the electronegativity of the atoms being bonded is between .3 and 1.7 the type of bond is considered to be covalent (when electrons are shared), more specifically, .3 - .9 are polar bonds (when certain parts are slightly negative or positive). one of the most common examples of this would be a water molecule.

Hope I helped you out, man. :)

sounds more like a she u know "sophipie27" doesn't sound like a username a self respecting guy would use...(no offence if you're actually a guy) ^_^

well my bad i wasn't paying attention to the username

lol just bugging you. =P

In the simplest model, the degree of polarity of a covalent bond is determined by the relative difference in electronegativity of the two atoms. Therefore, something like the carbon-carbon bond in ethane CH3-CH3 would be virtually zero polarity, as the two atoms are the same (both carbon), and the type and symmetry of the other atoms bonded to each carbon (3 hydrogens in each case) are the same.

On the other hand, the carbon-oxygen bond in ethanol, CH3-CH2-OH is significantly more polar, due to the high electronegativity of oxygen compared to that of carbon.

Thanks guys!

and yes i am a girl =]

HAHA i was right!
