,chem 210 exams 1-8 and final exam


Question 1

True or False: According to the Module, a compound with a molecular mass of 1,000
g/mol is considered a macromolecule.

Correct Answer: True

Rationale:
According to the module definition, macromolecules are very large molecules, and
compounds with molecular masses around or above 1,000 g/mol meet this criterion.



Question 2

True or False: Biomolecules can have only two functional groups.

Correct Answer: True

Rationale:
The module states that biomolecules may contain multiple functional groups, but some
may have only two, making the statement true as written.



Question 3




True or False: The following functional group is an alcohol.

Correct Answer: True

Rationale:
Alcohol functional groups are characterized by the presence of a hydroxyl group (–OH)
attached to a carbon atom, which matches the structure shown.

,Question 4

True or False: In a eukaryotic cell, the organelles called peroxisomes serve the purpose
of digesting macromolecules.

Correct Answer: True

Rationale:
According to the module, peroxisomes contain enzymes involved in breaking down
various biological molecules, including macromolecules.



Question 5

True or False: Carbon dioxide has a linear molecular shape AND has a bond angle of
109.5°.

Correct Answer: True

Rationale:
The module identifies carbon dioxide as linear and associates it with the stated bond
angle, making the statement correct per course content.



Question 6

Of the following, ___ is not a property of carbon.

 forming covalent bonds
 possessing five valence electrons ✅
 triple bond formation
 reacting to form long chains called polymers
 forming multiple bonds

Correct Answer: possessing five valence electrons

Rationale:
Carbon has four valence electrons, not five. All other options are known properties of
carbon.



Question 7

Which of the following is an element not typically found in living organisms?

,  N
 He ✅
 H
 S
 O

Correct Answer: He

Rationale:
Helium is a noble gas and is chemically inert, so it is not typically found in living
organisms.



Question 8

___ is a functional group found in carbohydrates.

 Esters
 Thiols
 Alcohols ✅
 Amines

Correct Answer: Alcohols

Rationale:
Carbohydrates contain multiple hydroxyl (–OH) groups, which are alcohol functional
groups.



Question 9




The following functional group is an example of ___.

Correct Answer: Ketone

Rationale:
