Polymerisation — Chemistry 9701 AS & A Level Question & Worked Solution

(a(i))

Draw a section of the PVA molecule containing at least 2 monomer units, and identify the repeat unit clearly.

(a(ii))

Use this information to suggest one possible structure for $C$ and draw it in the box above.

(a(iii))

Suggest a structure for $C$ that matches this new information.

(a(iv))[6]

Suggest a confirmatory test for the functional group in the structure you drew in (iii). Your answer should include the reagent used and the observation made.

(b(i))

On the formula above, draw brackets [ ], around the atoms that make up the repeat unit of this polymer.

(b(ii))

Name the functional group in polymer $D$.

(b(iii))

Suggest and draw the structure of monomer, $E$, that could form this polymer.

(b(iv))

What type of polymerisation is involved in making polymer $D$ from its monomer?

(b(v))[5]

What is the relationship between the repeat unit of polymer $D$ and the repeat unit of PVA?

(c(i))

Name the type of stereoisomerism shown by compound $E$.

(c(ii))[4]

Suggest structures for $F$ and $G$, and name the type of stereoisomerism they show.
