Question 8
Which substance has no delocalised electrons? A graphite B methylbenzene C poly(propene) D sodium
Worked Solution & Example Answer:Which substance has no delocalised electrons? A graphite B methylbenzene C poly(propene) D sodium - AQA - A-Level Chemistry - Question 8 - 2022 - Paper 3
Step 1
C poly(propene)
Answer
Poly(propene), also known as polypropylene, is a polymer formed from the polymerization of propene monomers. Unlike substances with delocalised electrons, such as graphite and benzene, poly(propene) has a saturated structure with no π-bonds that would allow for delocalization. Thus, it does not possess delocalised electrons.
