ionic character

Postby connie 2C » Thu Nov 07, 2019 4:50 pm

in 2d.5, when it states to determine which bonds have the greater ionic character, is it asking the which has the greater difference in electronegativity?

Yes, I believe ionic character is proportional to difference in electronegativity since the atoms will not be sharing the electrons equally if the electronegativity is greater; one atom will have a greater pull.

yes, a larger difference in electronegativity would indicate more ionic character, while a smaller difference indicates more covalent character.

Since electronegativity is the tendency of an atom to attract a shared pair of electrons towards itself, greater ionic character implies a greater difference in electronegativities.

So if the difference in electronegativity is greater than 2, then the bond is ionic?

Ionic character, I believe, is a covalently bond that has such strong ionic character (electronegativity) that a covalently bonded substance is almost ionic.

Yes. An ionic bond is any bond with a delta greater than 2 between the electronegativities of the two bonding elements.

Why does CF4 have greater ionic character than CH4?

If a molecule has more ionic character, is it soluble in water? Even if its a covalent bond?

I'm not sure what you mean by a covalent bond with ionic character?
