Peopl. think polymer is concept less topic if u too think so hav a look at it
Assertion:Nylon 6,6 is a copolymer
Reason: a copolymer is one that is build using two monomer,
in case of nylon 66 , 1,4 butane-dicarboxylic acid is a monomer but hexan-1,6 diamine is not
What do u get??[1][1]

11what i'm saying is.....not everyone refers the trustworthy source you refer to......so I don't think that JEE ppl (or you) shd frame a ques'n based on such a thing....
NOT THAT WHAT U DID WAS WRONG.......JUST THAT THE DEF'N IS OPEN FOR DEBATE.....
1no dude i don't know waht the jee people are thinking,but i know 1 thing ,definitions never change as they are the building blocks of a subject ,for trust worthy definitions see trustworthy sources,i don't know whther this sort of ques. will come or not but i wanted to say that conceptual questions can be framed from anywhere
11I read them......but do u really think everyone in India read that def'n of a polymer?? Don't u think that IIt know well enuf not to take advantage of such multi-defenitive terms??
1hey read defn 1 and defn 2 they are taken from valuable sources ,then your dilemma should be solved
11Defenitions are subject to change everywhere, Grandma....i mean, Grandmaster [3]
1nylon 6,6 is formed frm condensation polymerisation( step growth)
and not frm chain growth !!!
then y the big confusion/??
11Why isn't hexan1,6diamine a monomer??? if it weren't for hexan1,6diamine, there wouldn't be any Nylon6,6 at all......Can u imagine a life without nylon6,6???? It would be appaling [11]

1hey dude the ans is
A is wrong
R is correct
Explantion
defn1: a monomer is a cmpnd that can form polymer by itself(i.e. alone by itself)
so hexane1,6diamine is not a monomer
defn2: a copolymer is one that is made up of 2 monomers .
As hexane1,6diamine is not a monomer(refer defn 1) so,nylon 6,6 is not a copolymer
21nice site eure!!!!!!! [1]
but hey wats ur ans den for the abov que, A or B.... as assertn n resun both turn out 2 b true, as per ur explanation..........
WAT SAY?
I wud go 4 B
24vaise u all chem lovers should visit this site............found it in the evening,,,,,,,,,http://www.ben.mills.btinternet.co.uk/chemistry/dict.htm
lots of definitons....[1]
24knowledge...........pada tha 2 months back........[3]i dont know ki vaise kaise pata lagate hain.....[1]
21DUDE : how do u decide wether hexan-diamine is mononmer or polymer??
24nooooooo hexan-1,6 - diamine is polymer..................so A is correct, R is incorrect
1dohnorite ahi
nylon 66 is a copolymer of adipic acid n hexamethyl diamine
24Reason: a copolymer is one that is build using two monomer,
in case of nylon 66 , 1,4 butane-dicarboxylic acid is a monomer but hexan-1,6 diamine is not
ye pura reason ha kya?????????????????????[7]
