Question 11

Two alkene monomers, P and Q, undergo addition polymerisation.

MonomerFormula
PCH2=C(CH3)CH2CH2CH3\text{CH}_2\text{=C(CH}_3\text{)CH}_2\text{CH}_2\text{CH}_3CH2​=C(CH3​)CH2​CH2​CH3​
QCH2=CHCH2CH2CH3\text{CH}_2\text{=CHCH}_2\text{CH}_2\text{CH}_3CH2​=CHCH2​CH2​CH3​

Compare the numbers of carbon atoms and hydrogen atoms in one repeating unit of the polymer formed from P and one repeating unit of the polymer formed from Q. Explain your answer.
