no not really coz C was a little under the line....(pH 7) but there cannot be 2 answers so yeah I think its D
I lost 4 marks in total until now D:

Here is to prove that both alkene and alcohol can be present in a compound, NOV 10 Question 37
http://www.xtremepapers.com/papers/CIE/Cambridge%20IGCSE/Chemistry%20(0620)/0620_w10_qp_11.pdf
Answer was alkene and alcohol but no alkane

Answer was alkene and alcohol but no alkane

That's not a polymer !The question was about a polymer and homologus series..Here is to prove that both alkene and alcohol can be present in a compound, NOV 10 Question 37
http://www.xtremepapers.com/papers/CIE/Cambridge IGCSE/Chemistry (0620)/0620_w10_qp_11.pdf
Answer was alkene and alcohol but no alkane
I never read anything about polymer, he said to which homolgus series does this compound belong

The question started:
PVA is a polymer.Its monomer is shown below.
To which compound does this compound belong?
Lets wait ^^
ok you just said PVA is a polymer, so its monomer does polymerize, which means the answer none of alkene and alcohol is wrong. because the double bond is broken and the polymer is formed.
Yea its monomer was shown below and the monomer can have both the polymer cannot have both.....

How can a polymer belong to alkenes if saturated?
Again lets wait
It won't make a difference.
Again lets wait
It won't make a difference.
Why not ? Condensation polymerization is made from two different monomers
How can a polymer belong to alkenes if saturated?
Again lets wait
It won't make a difference.
Yea I guess we just have to wait but the question was asking and talking about the monomer of the polymer.....not the polymer itself.....
I am almost sure that Alcohol is wrong
but I said that it is alkene only because:
1-Addition polymerization is about linking monomers of Alkene to form poly alkene
2-There is a monomer called Vinyl chloride and it's polymer is called Polyvinyl chloride (PVC as an abbreviation) and it is mentioned in our syllabus ..... The only difference between PVC and PVA is that PVC have Cl instead of the OH of PVA
3-In a past test they said that alcohols can't be polymerized
Still not sure if Alkene only or non

Maybe but if they were asking about the polymer..Alkene is impossible..Polymer can't belong to alkene since it is saturated..Maybe alcohol only or none at all..I am almost sure that Alcohol is wrong
but I said that it is alkene only because:
1-Addition polymerization is about linking monomers of Alkene to form poly alkene
2-There is a monomer called Vinyl chloride and it's polymer is called Polyvinyl chloride (PVC as an abbreviation) and it is mentioned in our syllabus ..... The only difference between PVC and PVA is that PVC have Cl instead of the OH of PVA
3-In a past test they said that alcohols can't be polymerized
Still not sure if Alkene only or non
It was unsaturated

Look as I remember the question was saying that PVA is a polymer made of monomer shown below which is CH2==CHOH
I am almost sure that Alcohol is wrong
but I said that it is alkene only because:
1-Addition polymerization is about linking monomers of Alkene to form poly alkene
2-There is a monomer called Vinyl chloride and it's polymer is called Polyvinyl chloride (PVC as an abbreviation) and it is mentioned in our syllabus ..... The only difference between PVC and PVA is that PVC have Cl instead of the OH of PVA
3-In a past test they said that alcohols can't be polymerized
Still not sure if Alkene only or non
they were asking about the monomer, and alcohols can polymerise who said they couldnt?? I mean polyesters.....even though condensation polymerisation is not in the syllabus they might have given it like 1 year they asked about the salt bridge in an MCQ....

Yeah then to which homologus series does this compound belong to..
Again,won't make any difference when until the ms are published,won't make any difference now..
it belongs to a completely different homologuous series not alkenes and not alcohols, but it has both of their functional groups.....
