(a)
Interpretation:
The condensed structural formula for the product of reaction between terephthalic acid and ethylene glycol in the 1:1 ratio needs to be determined.
Concept Introduction:
(b)
Interpretation:
The condensed structural formula for the product of reaction between the product in part (a) and 1 mol of ethylene glycol needs to be determined.
Concept Introduction:
Polymers are formed by polymerisation of certain monomer units. Based on type of chemical reaction, polymerisation can be two types; condensation polymerisation and addition polymerisation. Addition polymerisation occurs between unsaturated monomer units whereas condensation polymerisation occurs with elimination of water molecule as by-product between two functional groups. PETE is an example of condensation polymer.
(c)
Interpretation:
The mass of PETE recycled in one year needs to be determined.
