Question 1
This question is about ethanoic acid (HOOCCHOH) and the ethanoate ion (−OOCCHO−). Ethanoic acid reacts with propane-1,3-diol (HOCH2CH2CHOH) to form a polyester. Dr... show full transcript
Worked Solution & Example Answer:This question is about ethanoic acid (HOOCCHOH) and the ethanoate ion (−OOCCHO−) - AQA - A-Level Chemistry - Question 1 - 2021 - Paper 3
Step 1
Draw the repeating unit of this polyester
Answer
The repeating unit of the polyester formed from the reaction of ethanoic acid and propane-1,3-diol can be represented as follows:
O O
|| ||
HOOC−C−C−C−C−OH
| |
H H
In this structure, the ethanoate group (-OOC-) connects with the propane-1,3-diol structure, forming the polyester linkage.
