Q

how do you test for alkenes?

A

burn it and it should have a smokier, yellower (brighter) flame
when reacting alkenes with bromine water, the solution changes from orange to colourless

Q

how are polymers formed?

A

When alkene molecules join, the covalent double bond opens up/breaks
This creates bonds on the two carbon atoms on either side of the double bond
This becomes saturated when monomers join together
The polymer chains are made up of a C backbone

16
Q

what is the process where polymers are formed called

A

This type of reaction is called addition polymerisation

17
Q

what does mono mean

A

Mono = one

18
Q

what does poly mean

A

poly = many

19
Q

how many products are formed in addition to polymerisation

A

in addition polymerisation, there is only one product formed, which is the polymer.

20
Q

what does a repeating unit have

A

A repeating unit has trailing bonds

21
Q

what does the n represent

A

n represents how many paperclips are in the paperclip chain (how many repeating units are in the polymer

22
Q

What to make sure for a repeating unit: 4

A

the formula is drawn correctly (correct number of C and H
Trailing bonds
Brackets
n outside

23
Q

what are two types of condensation polymers

A

Polyester and nylon are condensation polymers

24
Q

how many products does condensation polymerisation produce and what products does it produce

A

in condensation polymerisation, there are two products, one of which is a small molecule like water or hydrogen

25
Q

whatis the second product that nylon produces?

A

When nylon is made the second molecule produced is HCl

26
Q

what are monosaccharides

A

Monosaccharides are made up of one sugar units

27
Q

give examples of monosaccharides

A

Examples of monosaccharides are glucose, and fructose

28
Q

how many ring structures does glucose have

A

Glucose molecules are made up of six membered ring structures (hexagonal structures)

29
Q

how many ring structures does fructose have

A

Fructose - F for Five - made up of 5 membered rings

30
Q

what two monosaccharides are sucrose made of

A

Sucrose = glucose +fructose

31
Q

what are polysaccharides

A

Polysaccharide = polymer of thousands of monosaccharides

32
Q

what two functional groups do amino acids have

A

basic group - amine group - NH2
Acidic group - carboxylic acid - COOH

33
Q

what does dna stand for

A

DNA = Deoxyribonucleic Acid

34
Q

what does dnas structure contain

A

DNA’s structure contains genetic code that determines the different amino acids of every protein

A

DNA = condensation polymer

36
Q

what is the name of dna polymer

A

The monomers of DNA = nucleotides

37
Q

how are the two strands of dna held together

A

they are held together by the intermolecular forces that run down the length of them

38
Q

what are the bases of dna

A

The complimentary bases are AT and CG - remember the mnemonic AT Chelsea’s Grounds

39
Q

what are the name of the bases

A

Adenine
Thymine
Cytosine
Guanine
