Front (Question)

Condensation polymerisation

Back (Answer)

Joining two monomers with the loss of a small molecule e.g. H2O or HCl. Requires two DIFF functional group; no carbon-carbon bonds

Front (Question)

What are polyesters joined by

Back (Answer)

Ester linkages - COO

Front (Question)

Forming an ester w/ one monomer

Back (Answer)

Must have both -COOH/-OH groups (hydroxycarboxylic acid) or two -COOH/-OH (dicarboxylic acid/ diol) OH group from -COOH and H from -OH form water

Front (Question)

Forming a polyester w/ two diff monomers

Back (Answer)

Must be a diol or dicarboxylic acid/ di acyl chloride

Front (Question)

Uses of polyesters

Back (Answer)

Clothing Electrical insulation Plastic bottles

Front (Question)

What are polyamides joined by

Back (Answer)

Amide linkages - CONH

Front (Question)

Forming polyamides from one monomer

Back (Answer)

Must have both -COOH and -NH2 (amino acids)

Front (Question)

Forming polyamides from two diff monomers

Back (Answer)

Dicarboxylic acid/ diacyl chloride w/ diamine

Front (Question)

Naming diacyl chloride

Back (Answer)

Longest carbon chain dioyl chloride

#10

Front (Question)

Naming hydroxycarboxylic acids

Back (Answer)

no attached to -OH hydroxy longest chain oic acid

#11

Front (Question)

Naming diamines

Back (Answer)

N,N diamino longest chain

#12

Front (Question)

Acid hydrolysis of polyesters (H+/H2O)

Back (Answer)

Reforms monomers

#13

Front (Question)

Alkali hydrolysis of polyesters (NaOH/H2O)

Back (Answer)

Forms -ol/-diol and carboxylate salt

#14

Front (Question)

Acid hydrolysis of polyamides (H+/H2O)

Back (Answer)

Forms protonated amine groups and -COOH

#15

Front (Question)

Alkali hydrolysis of polamides (NaOH/H2O))

Back (Answer)

Forms carboxylate salt and -NH2

#16

Front (Question)

Formation of nitriles

Back (Answer)

Using haloalkanes Using ketones/aledehydes

#17

Front (Question)

Formation of nitriles w/ haloalkanes

Back (Answer)

Reacting NaCN in ethanol w/ a haloalkane Nucleophilic sub (substitutes a functional group, not just H)

#18

Front (Question)

Formation of nitriles w/ ketones/ aldehydes

Back (Answer)

Reacting w/ HCN (poisonous so NaCN and H2SO4 is used instead) Forms a hydroxynitrile

#19

Front (Question)

Reduction of nitriles

Back (Answer)

Longest chain nitrile + 2 H2 (Ni)—> Amine

#20

Front (Question)

Hydrolysis of nitriles

Back (Answer)

nitrile + 2H2O + dilute aq acid (heat) —> -COOH and ammonium salt

#21

Front (Question)

Ways to increase carbon chain length w/ benzene

Back (Answer)

Alkylation - haloalkane and Friedel crafts catalyst Acylation - acyl chloride w/ Friedel Crafts catalyst

#22

Front (Question)

Acylation w/ acid anhydrides e.g. C4H6O3

Back (Answer)

Still requires a Friedel-Crafts catalyts C2H3OOAlCl3- and C2H3O+ 2H3OOAlCl3 - and H+ —> -COOH and AlCl3
