35
Q

Saturated

A

Single bonds

36
Q

Unsaturated

A

double bonds

37
Q

Constitutional (structural) isomers

A

Have the same molecular formula but the atom has diffrent connectivity.

38
Q

Stereoisomers

A

Any two molecules that have the same connectivity between the atoms but atoms are arranged diffrently in space

39
Q

conformatinal Isomers

A

diffrent only by a rotation of a single bond

40
Q

Cis

A

atoms on same side of molecule

41
Q

trans

A

atoms on diffrent sides of the molecule

42
Q

If there is an ionic bond

A

Show the ion as separate and charged

43
Q
A

Aromatic Ring

44
Q

Acids

A

Proton (H) donator

45
Q

Base

A

Proton (H) acceptor

46
Q

What happens to H₂CO₃

A

It is not stable so it decomposes into water and carbon dioxide

47
Q

Solubility Rule of Thumb

A

Need <4 carbons per H binding functional group to be solule in water

48
Q

Hybrid Atomic Orbital: SP

A
  • Linear VSEPR
  • 2 unused p-orbial
  • Double or triple bond
49
Q

Hybrid Atomic Orbital: SP2

A
  • Trigonal Planar VSEPR
  • 1 unused p-orbial
  • Double bond
50
Q

Hybrid Atomic Orbital: SP3

A
  • Tetrahedral VSEPR
  • 0 unused p-orbial
  • single bonds
51
Q

Delocalization of electrons (conjugation and resonance) is stablilizing

A
52
Q

LUMO

A

lowest unoccipied molecular orbial

53
Q

HOMO

A

Highest occupied molecular orbital

54
Q

the smaller the HOMO, LUMO gap

A

the longer the wavelenght

55
Q

Congucation leads to

A

a smaller HOMO-LUMO gap

56
Q

Calculating Formal Charge

A

valence shell electrons(free atom)-#lone pair electrons - 1/2 # bonding electrons

57
Q

Coordinate covalent bond

A

where electrons are coming from one atom/molecule and are going to the metal

58
Q

Ligands

A

Atoms/molecules that are binding to the metal

59
Q

Chelating Ligands

A

can bond more than once (multiple doantion sites)

60
Q

Cordination number

A

number of groups bonded to the metal

61
Q

Stability Rules

A
  • octet rule-All atoms have there octet unless ir is 3rd period or lower then it can have an expanded octet
  • Minimize formal charges
  • Have negative charge on the more electronegative atoms
62
Q

Boiling Point

A
  • the stronger the IMFs the higher the boiling point (and melting point)
  • IMFs= the bonds molecules can make with other molecules
  • Hydrogen bonds - strong happen between N,O,F and hydrogen
  • Dipole-Dipole
  • Dispersion forces - weak
