Chapter 4: Analyzing Organic Reactions Flashcards
Ka (acid dissociation constant
Ka = [H+][A-] / [HA]
pKa
pKa = -log Ka
Amphoteric
Al(OH)3, HCO3^- and HSO4^-
Functional groups tha act as a acid
alcohols, aldehydes and ketones
Functional groups tha act as a base
amines and amides
Bond strength decreases downt hr periodic table
acidity increases
alpha-hydrigen in a alpha-carbon (which is a carobon adjacent to the carbonyl)
these are acidic hydrogens that are easily lost
most nucleophiles
CHON with a negative sign
things thta affect nucleophilicity
1)Charge
2)electronegativity
3)steric hindrance
4)solvent
polar protic
solvent increases down the periodic table
polar aprotic
solvent increases up the periodic table
polar protic
I > Br > Cl > F
polar aprotic
F > Cl > Br > I
Good leaving groups
I- Br- and Cl-
Sn1 reactions
Step 1: formation of carboaion
Step 2: nucleophilic attack
