Condensation

• What is a condensation polymer?


  A condensation polymer is formed when monomers react and lose small molecules such as water.
• What is a condensation polymer?


  A condensation polymer is formed when monomers react and lose small molecules like water.
• How do condensation polymers differ from addition polymers?

  Condensation polymers are formed from monomers that are not alkenes and lose small molecules during the reaction.
• How do condensation polymers differ from addition polymers?

  Condensation polymers are formed from monomers that are not alkenes and lose small molecules during the reaction.
• What are the two types of functional groups present in the monomers used to form a condensation polymer in the example provided?

  Alcohol groups and carboxylic acid groups.
• What are the two types of functional groups present in the monomers used to form a condensation polymer?

  Alcohol groups and carboxylic acid groups.
• What are the names of the two monomers used in the example of condensation polymer formation?


  The two monomers are ethane-1,2-diol and hexane-1,6-dioic acid.
• What is the first step in forming a condensation polymer?

  The first step is to start with two different monomers, each having two of the same functional groups.
• What happens when ethane-1,2-diol reacts with hexane-1,6-dioic acid?

  They react to form an ester and water.
• What are the two monomers used in the example of a condensation polymer discussed in the video?

  Ethane dial and hexane dioic acid.
• What is produced alongside the condensation polymer during the reaction of the two monomers?

  Water molecules are produced.
• What happens when ethane dial reacts with hexane dioic acid?

  They react to form an ester and water.
• How can the structure of a condensation polymer be represented in terms of its repeating unit?

  The repeating unit is drawn with brackets around two adjacent monomer units, with a bond crossing through each bracket and an 'n' to indicate a large number.
• What is the significance of water molecules in the formation of condensation polymers?

  Water molecules are produced as a byproduct when monomers react to form the polymer.
• If 1,000 molecules of both monomers are used, what is the value of 'n' in the repeating unit?

  In this case, \( n = 1000 \).
• What is a polyester?

  A polyester is a type of condensation polymer formed from the reaction of diols and dicarboxylic acids.
• What is the process of forming a condensation polymer from two different monomers?

  • Start with two different monomers, each with two of the same functional groups.
  • React the monomers to form an ester and water.
  • Continue adding monomers to form a long polymer.
  • Water molecules are produced during the reaction.
• How do you draw the repeating unit of a condensation polymer?

  You draw two adjacent monomer units, place brackets around them, and indicate a large number with an 'n' to show repetition.
• What are the key characteristics of condensation polymers?

  • Formed from monomers that are not alkenes.
  • Involves the loss of small molecules (e.g., water).
  • Can produce long chains of polymers.
  • The repeating unit can be represented with brackets and 'n'.
• In the example given, how many molecules of each monomer are used to form the repeating unit?

  1,000 molecules of each monomer.
• What does the letter 'n' represent in the context of a repeating unit of a condensation polymer?

  The letter 'n' represents a large number indicating how many times the repeating unit occurs in the polymer.
• What are the steps involved in forming a condensation polymer?

  1. Start with two different monomers, each with two of the same functional groups.
  2. React the monomers to form an ester and water.
  3. Continue adding monomers to form a long polymer chain.
  4. Water molecules are produced during the reaction.
• What should you do if asked to draw the repeating unit of a condensation polymer in an exam?

  • Identify two adjacent monomer units.
  • Draw them out and place brackets around them.
  • Indicate the repetition with 'n' to the right of the brackets.
