Question 15

A materials technician writes an equation for making a polymer from the monomer CH2=CHF\text{CH}_2\text{=CHF}CH2​=CHF. What is the correct equation?

[1]
A

n CH2=CHF→[-CH2-CHF-]nn\,\text{CH}_2\text{=CHF} \rightarrow \left[\text{-CH}_2\text{-CHF-}\right]_nnCH2​=CHF→[-CH2​-CHF-]n​

B

n CH2=CHF→[-CH2-CH2-]nn\,\text{CH}_2\text{=CHF} \rightarrow \left[\text{-CH}_2\text{-CH}_2\text{-}\right]_nnCH2​=CHF→[-CH2​-CH2​-]n​

C

n CH2=CHF→[-CHF-CHF-]nn\,\text{CH}_2\text{=CHF} \rightarrow \left[\text{-CHF-CHF-}\right]_nnCH2​=CHF→[-CHF-CHF-]n​

D

n CH2=CHF→[-CH2=CHF-]nn\,\text{CH}_2\text{=CHF} \rightarrow \left[\text{-CH}_2\text{=CHF-}\right]_nnCH2​=CHF→[-CH2​=CHF-]n​
