Q

best resonance when given carbonation or anion

A

just push the charges to the next carbon for resonance (flip) ** see page 1

Q

best resonance for radical

A

draw three arrow pushing structures to shift the bonds. the most stable is gonna be the one with the least interruption of the =/= bond alternation see page 1

Q

newman projection steps

A
  1. draw out the full line structure
  2. draw an EYE from where you look
  3. draw the circle and the Y. the dot in the centre of the Y is the first carbon the eye sees. then the branches are what it is bonded to. then draw the back circle with the biggest atoms as far away from each other

** see back of page 1

Q

how to draw chair conformation and H

A
  1. draw to parallel lines =
  2. add two more parallel lines at 109.5 degrees from before the other ones
  3. connect the two with 2 more parallel lines
  4. look at what parts point up and down, and add axial up and down accordingly
  5. look at the axial stuff and draw equatorial in general opposite direction to get kind of a < shape

23
Q

why are Equatorial planes more stable in chair confirmations

A

because of 1,3 diaxial interactions

- axial are separated by only one carbon, while eq are separated by more angle making them more stable for LARGER atoms

24
Q

ring strain chair confirmation

A

when the cyclohexane interior angles are more strained that the outside angles

25
Q

cis and trans cyclohexanes

A

cis is same direction

26
Q

bronstead acid

A

donates H+

27
Q

lewis acid

A

accepts electrons

28
Q

conjugate base formula

A

Cb = H-1

29
Q

stronger the acid, the __ cb?

A

weaker

30
Q

stronger the base, the ___ ca?

A

weaker

31
Q

increased Ka, means what to aka and what to acid strength

A

decreased pKa, increased acid strength

32
Q

more stable the cb, the ___ the acid

A

stronger

33
Q

more stable the ca, the ___ the base

A

stronger

34
Q

pKa for the H on H2O

A

35
Q

pKa for the H on H3o+

A

40
Q

CARDIO

A

charge, atom, resonance, dipole induction and orbital hybridization to RANK ACIDS AND BASES

41
Q

Charge for ranking acids

A

more positive the compound, the more acidic

42
Q

Charge for ranking bases

A

more negative the compound, the more basic

43
Q

atom for ranking acid

A

acidity increases if

  • its electronegative
  • very big (MOST BIG FACTOR)
44
Q

resonance for acids

A

more stable the conjugate base, the stronger the acid

45
Q

resonance for bases

A

more stable the conjugate acid, the stronger the acid

46
Q

tip for resonance acids and bases

A

take away the H from the acid and see how stable the - charge is

47
Q

dipole induction for ranking acids and bases

A

bigger the dipole away from the H, means more acidic

48
Q

orbitals for ranking acids and bases

A

more S character, like closer to sp than sp3, is more acidic

49
Q

pH and protonation of functional groups

A

if the solution pH is lower than the pKa, the functional group will protonate

higher will deprotonate

50
Q

high acidity of amino acid

A

gets all protonated so its all h’d up

51
Q

neutral pH and amino acid

A

stays as NH3+ and O-

52
Q

high pH, amino acids

A

get lass protonated, and have as less H as possible

NH2, O-
