21

Base

A hydroxide (eg. sodium hydroxide) is an ACID/BASE?

22

27

Intramolecular Bonding

Bonding within a molecule is:

28

Ionic and covalent bonding

Two types of intramolecular bonding

29

Ionic Bonding

This involves the transfer of one or more e- between a metal and a non-metal

30

Ionic Bonding

change in E.N. that is >1.7 demonstrates:

31

Covalent Bonding

This involves the sharing of e- between two non-metals

32

atoms have the same E.N. and the bond is non-polar (i.e.. O2)

Equal sharing or polar bonds is when:

33

atoms have different E.N. and the bond is polar

Unequal sharing or polar-covalent bonds is when:

34

Covalent Bonding

change in E.N. between 0.5-1.7

35

-molecular shape (symmetry)
-the presence of polar bonds

Molecular Polarity depends on:

36

Ionic Bond

1.7-3.3 difference in E.N. is this type of bond

37

Intermolecular Bonding

Bonding between molecules that are weaker then intramolecular bonds:

38

London dispersion forces

temporary bonds between all molecules caused by the constant movement of e-'s and temporary charge imbalances

39

Dipole - Dipole

this happens only between polar molecules they are held together due to partial charges they are stronger then L-D forces

40

Hydrogen Bonding

this happens only between polar molecules it is the strongest of the three it induces strong h-bonds between nearby molecules

41

Hydroxyl

found in alcohols

42

Carbonyl

found in aldehydes or ketones

43

Carboxyl

found in acids

44

Amino

found in bases

45

Sulfhydryl

found in rubber

46

Phosphate

found in ATP
