Question 5
F

Poly(methyl methacrylate) is an addition polymer. Its repeating unit is [−CH2−C(CH3)(COOCH3)−]n\mathrm{[-CH_{2}-C(CH_{3})(COOCH_{3})-]_{n}}[−CH2​−C(CH3​)(COOCH3​)−]n​.

Which is the monomer?

[1]
A

CH3−CH(CH3)COOCH3\mathrm{CH_{3}-CH(CH_{3})COOCH_{3}}CH3​−CH(CH3​)COOCH3​

B

CH2=CHCOOCH3\mathrm{CH_{2}=CHCOOCH_{3}}CH2​=CHCOOCH3​

C

CH2=C(CH3)COOCH3\mathrm{CH_{2}=C(CH_{3})COOCH_{3}}CH2​=C(CH3​)COOCH3​

D

CH3CH=C(CH3)COOCH3\mathrm{CH_{3}CH=C(CH_{3})COOCH_{3}}CH3​CH=C(CH3​)COOCH3​
