Question
Identify the monomer from the repeat unit of the addition polymer shown as -[CH2-CH(CH3)]-.
Answer
The monomer for this addition polymer is propene (C3H6).
Explanation
This question assesses the ability to deduce the monomer from a given repeat unit. The repeat unit -[CH2-CH(CH3)]- suggests that the polymer is derived from propene, which has the molecular formula C3H6, indicating the presence of a methyl group in the structure.
Common mistake
Identifying Monomers from Repeat Units
Students often confuse the repeat unit of an addition polymer with the monomer it originated from, leading to incorrect identification.
To correctly identify the monomer from a repeat unit, first recognize the structure of the repeat unit, then determine the original alkene by removing the bonds that connect the repeat units and adjusting for any hydrogen atoms lost during polymerization. For example, if the repeat unit is -CH2-CH2-, the corresponding monomer is ethene (C2H4).
