Two alkene monomers, P and Q, undergo addition polymerisation.
| Monomer | Formula |
|---|---|
| P | CH2=C(CH3)CH2CH2CH3\text{CH}_2\text{=C(CH}_3\text{)CH}_2\text{CH}_2\text{CH}_3CH2=C(CH3)CH2CH2CH3 |
| Q | CH2=CHCH2CH2CH3\text{CH}_2\text{=CHCH}_2\text{CH}_2\text{CH}_3CH2=CHCH2CH2CH3 |
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.
