Does electronegative atoms cause shielding or deshielding of the atoms near it? (Deshielding, because shielding is caused by electrons. - GS). If there is deshielding then it is upfield and there is less of a chemical shift and if there’s shielding it’s more downfield and has more of a chemical shift correct? Am I backwards on this or do I have it correct? Thanks. (It is backwards, because shielding requires more field to overcome the shielding, so it is upfield. - GS).
