Lesson 6: Structural Effects On ACIDITY Flashcards
(15 cards)
Concept of Electronegativity
More electronegative, more acidic
Concept of hybridization
More s character, more acidic
Which is more acidic, sp or sp3?
Sp
3 concept inductive effects
Distance, number, hybridization
Stabilizing
Electron-withdrawing groups
Destabilizing
Electron-donating groups
Concept of distance
Closer the EWG to the acidic H, more acidic
Concept of number
More EWG, more acidic
Concept of hybridization
More s character, more acidic
Electron-donating groups concept D&I
Decrease acidity, increase basicity
The more the extra group, the ____ the acid
Weaker — Electron-donating group
Concept of steric effect
More big bulky groups, weaker the acid
More simple, more acidic
More big bulky groups, weaker the acid. Because?
Can’t release the H+ easily
In size, the larger the atom, __________
The stronger the acid
Concept of delocalization/resonance
More resonance structures, more stable, more acidic.
