Homologous series; naming; addition polymerisation: แบบฝึกหัด

Members of a homologous series share similar chemical properties and can be represented by a common general formula. Which of the following correctly identifies the fixed unit by which successive members in a series differ in their molecular formulae?

Which of the following represents the correct repeating unit of the addition polymer formed from pent-2-ene?

An organic monomer has the condensed structural formula:
\(\mathbf{CH_3CH=C(CH_2CH_3)CH(CH_3)_2}\)
Which of the following correctly identifies the systematic (IUPAC) name of this monomer and the repeating unit of the addition polymer formed from it?

Which of the following properties is common to all members of any homologous series?

What is the systematic IUPAC name for the organic compound with the structural formula \( (CH_3)_2CHCH=CH_2 \)?

Deduce the systematic IUPAC name of the monomer required to produce an addition polymer with the repeating unit \( \text{—[CH(CH}_3\text{)—C(CH}_3\text{)}_2\text{]}_n\text{—} \), and explain why this monomer has a higher boiling point than its lower homologue, 2-methylpropene.

Identify the systematic name of the monomer that corresponds to the addition polymer repeating unit \( \text{—[CH(CH}_3\text{)CCl(CH}_3\text{)]}_n\text{—} \), and explain how this monomer relates to 2-chlorobut-1-ene in terms of its molecular formula and structural arrangement.

Consider a section of an addition polymer used in high-performance adhesives, which has the repeating unit \( \text{—[CH}_2\text{—C(CN)(COOCH}_3\text{)]—} \). Deduce the systematic IUPAC name of the monomer used to form this polymer and identify the homologous series to which it belongs based on its principal functional group.
