29
Q

Define molecule formula

A

Shows the actual number of atoms of each element in a compound

30
Q

Define empirical formula

A

The simplest whole number ratio of atoms of each element in a compound

31
Q

Define structural formula

A

Show how the atoms are joined together in a molecule

32
Q

Define displayed formula

A

Shows every atom and every bond in a molecule

33
Q

Define skeletal formula

A

Uses lines to represent bonds

Alphabetical

No

36
Q

A
2- di
3- tri
4- tetra
5- penta
6- hexa
37
Q

Define structural isomerism

A

Same molecular formula but different structural formula

38
Q

Define stereoisomerism

A

Same structural formula but a different arrangement in space

39
Q

3 kinds of structural isomerism

A

Chain
Position
Functional group

40
Q

2 types of stereoisomers

A

Geometric

Optical

41
Q

Define chain isomerism

A

Same molecular formula but different length Carbon chain

42
Q

Define position isomer

A

Same molecular formula and same length C chain but functional group is attached at different positions along the chain

43
Q

Define functional group isomerism

A

Same molecular formula but different functional group

44
Q

Define a) general formula

b) Molecular formula

c) empirical formula

A

Shows the number of atoms of each element in a substance with n carbon atoms

Shows the actual number of atoms of each element

Simplest whole number ratio of atoms of each element

45
Q

Define structural formula

Define displayed formula

A

Shows how the atoms are joined together in a molecule

Shows every atom and every bone in the molecule

46
Q

What does IUPAC stand for

A

International Union for Pure and Applied Chemistry

47
Q

What are priority rules for E Z

A

Stage 1: consider atomic number of atoms on left side carbon of C=C
High atomic number takes priority
If both atoms the same consider atoms 1 bond further away. Atom with higher atomic number takes priority

Stage 2: repeat for RHS
Stage 3: if Priority on the same side =Z of on opposite = E

48
Q

How are stereoisomers used in biology?

A

Enzymes catalysed reactions result in stereospecific products

eg (+) glucose can be digested but (-) glucose cannot
One enantiomer of aspartic acid tastes sweet whereas the other tastes bitter
DRUGS - (lock and key model)

49
Q

How would you overcome the problem of a racemic mixture for drugs?

A

Separate isomers which is difficult because they have the same chemical properties

Sell the drug as a mixture (but half is useless)

Only make the required isomer

50
Q

What was the problem for thalidomide?

A

The body could convert the useful enantiomer into the dangerous one naturally
