CHEM 210 - Biochemistry - Module 1
with questions and well verified
answers actual exam!!! 2026
What do Biochemists study? - ANSWER -1. The relationship between structure and
function of biomolecules
2. Chemical reactions of organisms
3. Communication within and among organisms
Smaller elements are favored because they can form stable covalent bonds. T or F -
ANSWER -True. Strong bonds form by significant overlap of atoms, such as carbon and
hydrogen, allowing them to share electrons.
What is the bond angle of a Linear molecule? - ANSWER -180 degrees
What is the bond angle of a Trigonal Planar? - ANSWER -120 degrees
What is the bond angle of a Trigonal Pyramidal? - ANSWER -107.5 degrees
what is the bond angle of Tetrahedral? - ANSWER -109.5 degrees
What is carbon referred to in the chemical world? - ANSWER -The superglue
, What does organic chemistry study? - ANSWER -Focuses on the chemical and physical
properties of carbon compounds
What does inorganic chemistry study? - ANSWER -The field dealing with metals,
minerals, and other non-organic compounds
How many bonds can a Carbon form? - ANSWER -4! Due to having 4 valence electrons
What is a long chain of carbons called? - ANSWER -Polymers
What is a cyclic compound? - ANSWER -Carbons joined together in a closed chain
What are carbon compounds called? - ANSWER -Alkanes
Condensed structures give a better idea of a molecules structure, compared to chemical
formula. T or F - ANSWER -T
Structural formula gives an even better idea of a molecules structure, compared to chemical
formula - ANSWER -T
Advantage of cyclic carbon compounds - ANSWER -They are more restricted in their
movements and orientation - advantageous for building structures and maintaining shape
Carbon can form double and triple bonds with other carbon atoms or atoms of other
elements. T or F - ANSWER -T
Line-bond Drawing - ANSWER -Most efficient method to show structure, but requires
the most interpretation.
Functional group - ANSWER -specific arrangement of atoms; they define the chemistry
of the molecule and control the properties of the compound.
