Question 13

HDPE stands for ______________ polyethylene.
A) high definition
B) high density
C) hydrocarbon-derived
D) hydrogen density
E) hydrogen decoupled

Accepted Answer

HDPE stands for high density polyethylene, which is a type of thermoplastic made from petroleum.

Question 14

Why is HDPE tougher and more rigid than LDPE?
A) LDPE is a condensation polymer, while HDPE is an addition polymer.
B) HDPE is a condensation polymer, while LDPE is an addition polymer.
C) The two polymers are made of different monomers.
D) LDPE is made of linear chains, while HDPE is made of branched chains.
E) HDPE is made of linear chains, while LDPE is made of branched chains.

Accepted Answer

HDPE is made of linear chains which pack closely together, resulting in stronger intermolecular forces and a more rigid structure, while LDPE has branched chains that prevent tight packing, making it less rigid.

Question 15

The size of large biological polymers was first measured through a process called
A) X-ray crystallography.
B) condensation.
C) sedimentation.
D) dispersion.
E) capillary electrophoresis.

Accepted Answer

Sedimentation was one of the first methods used to measure the size of large biological polymers, such as proteins and nucleic acids, by observing their behavior in a centrifugal field.

A) Louis Pasteur
B) James Watson
C) Alexander Fleming
D) Dorothy Hodgkin
E) Theodor Svedberg

Accepted Answer

Theodor Svedberg won the Nobel Prize in Chemistry in 1926 for his work on the ultracentrifuge and studies of colloids and macromolecular compounds.

Question 17

Choose the true statement.
A) The monomer of an addition polymer must contain a functional group such as carboxylic acid or amine.
B) HDPE is more flexible than LDPE.
C) HDPE is made up of branched polymer chains.
D) An addition polymer results from adding monomers together, with no addition or removal of atoms.
E) none of the above

Accepted Answer

An addition polymer is formed by the addition of monomers with unsaturated bonds, such as alkenes, without the loss or gain of atoms.

Question 18

Polyesters are made from condensation reaction between which functional group on the monomer(s)?
A) two alcohols
B) a carboxylic acid and an alcohol
C) two carboxylic acids
D) two esters
E) an amine and a carboxylic acid

Accepted Answer

Polyesters are formed through a condensation reaction between a carboxylic acid and an alcohol, resulting in the formation of ester linkages.

Polyamides are made from condensation reaction between which functional group on the monomer(s)?
A) two alcohols
B) a carboxylic acid and an alcohol
C) two carboxylic acids
D) two esters
E) an amine and a carboxylic acid

Accepted Answer

Polyamides are formed through a condensation reaction between an amine group and a carboxylic acid group, resulting in the formation of an amide bond.
