acid trends Flashcards
acidity and electronegativity
stronger acid has its proton attached to the more EN atom
hybridization and acidity
less hybridization (more s character) = more acidic
size of atom and acidity
the stronger acid will have its hydrogen attached to the larger atom
what is the inductive effect?
EN atoms are present in the compound but are not directly bonded to the H that is to be donated
the EN atom pulls e- towards itself away from the pacific H, making its bond weaker and more acidic
If two compounds being compared have different electron withdrawing substituent(s)…
the compound with the more electronegative substituent will be the stronger acid.
If the two compounds being compared have the same electron withdrawing substituent(s)…
the compound with substituent(s) closer to the hydrogen that will be lost will be the stronger acid.
resonance is the ability of a molecule to…
delocalize electrons over two or more atoms
