#1
Front (Question)

How are condensation polymers formed And give 2 examples of condensation polymers

Back (Answer)

2 molecules react together with elimination of small molecule Polyesters and polyamides are polymers formed using this mechanism

#2
Front (Question)

In order for condensation reaction occur

Back (Answer)

2 func groups react with each other

#3
Front (Question)

One of way of forming polyester

Back (Answer)

Dicarboxylic acid + diol

#4
Front (Question)

Ester linkage

Back (Answer)

O // C \ O

#5
Front (Question)

3 ways of forming polyester

Back (Answer)

dicarboxylic acid + diol Single monomer (COOH + OH func group present)

#6
Front (Question)

the repeating unit for a polyester made from a diacarboxylic acid and diol contains

Back (Answer)

2 carbonyl groups 2 oxygen groups the atoms between 2 oxygen groups the atoms between 2 carbonyl groups

#7
Front (Question)

polyesters can be made from a singe monomer containing …

Back (Answer)

carboxylic acid functional group alcohol functional group

#8
Front (Question)

Explain using single monomers to form a polyester and use example

Back (Answer)

Lactic acid is an example of such monomer It contains -COOH + -OH groups that react to form esters Form polylactic acid Obtained from corn so biodegradable polymer

#9
Front (Question)

naming diols

Back (Answer)

Carbon stem then numbers then diol Eg propane - 1,3 - diol

#10
Front (Question)

Carboxylic acid + amine»_space;>

Back (Answer)

Amide + water

#11
Front (Question)

Acyclovir chloride + primary amine»_space;>

Back (Answer)

Amide + HCL

#12
Front (Question)

2 ways to form polyamides

Back (Answer)

Dicarboxylic acid + diamine or single monomer containg NH and COOH func group

#13
Front (Question)

amide link

Back (Answer)

O || C | N | H

#14
Front (Question)

Named example of polyamide

Back (Answer)

Kevlar

#15
Front (Question)

Kevlar made by

Back (Answer)

Reacting di carboxylic acid w benezne in the middle Reacting diamine w benzene in the middle

#16
Front (Question)

Uses of Kevlar and nylon

Back (Answer)

Strong Resistant for fire Flexible

#17
Front (Question)

Nylon can be formed w diamine and diacyldochlorife why is it not

Back (Answer)

More expensive and hcl gas

#18
Front (Question)

Are polyesters and polyamides biodegradable or not and why

Back (Answer)

Yes they are biodegradable As they can undergo hydrolysis to break the polymer down into the monomers Hydrolysis can be under acidic or basic conditions

#19
Front (Question)

C=O absorbs _______ making condensation polymers ________

Back (Answer)

C=O absorbs infrared radiation making condensation polymers photodegradable

#20
Front (Question)

Base hydrolysis of a polyester gives

Back (Answer)

Sodium salt of the Dicarboxylic acid And diol

#21
Front (Question)

Acid hydrolysis of a polyester gives

Back (Answer)

Dicarboxylic acid and diol

#22
Front (Question)

Base hydrolysis of a polyamide gives a

Back (Answer)

Sodium salt of a diacarboxylic acid and a diamine

#23
Front (Question)

Under acid hydrolysis conditions hydrolysis if polyamide gives

Back (Answer)

Diamine accepts proton to form ammonium ions and the Dicarboxylic acid is also formed
