AI Thread Summary
The discussion clarifies the distinction between polar and non-polar compounds, primarily based on electronegativity differences. Polar compounds arise when there is a significant electronegativity difference between atoms, leading to partial positive and negative charges and the formation of polar covalent bonds. These compounds are soluble in polar solvents like water. In contrast, non-polar compounds exhibit no electronegativity difference, resulting in symmetrical electron distribution and non-polar covalent bonds, making them insoluble in polar solvents. The presence of dipoles and their cancellation is also highlighted as a key factor in determining molecular polarity.

what is the difference between polar and non polar compounds
 
Chemistry news on Phys.org
One are polar, others are not?

Question is so vague that it is hard to tell what kind of information you are looking for.
 
that depends upon the electronegativity. if electronegativity of one element is greater than the other atom, then charge develops it is said polar compounds. if electronegativity is same, it is non polar

Carbon tetrachloride?

There are many differences between polar and non-polar compounds

Polar Compounds

-dissolve in water (because water is polar and polar liquids dissolve other polar substances)
-has an electronegetivity difference of less than 1.7
-has a polar covalent bond
-polar covalent bonds form when there is unequal electronegetivity because electrons spend their time closer to one atomic nucleus than another
-includes partial positive and partial negative bond dipoles

Non-polar compounds

-has an electronegetivity difference of 0 resulting in a non-polar covalent bond
-does not dissolve in any polar liquids such as water
-charges of electrons are distrubted symmetrically among the atoms in the molecules (no electronegetivity difference)


I hope this helps
 
Don't forget, if the dipoles
cancel out, the molecule is nonpolar.
