PREPARATION GUIDE FREQUENTLY TESTED
QUESTIONS WITH VERIFIED SOLUTIONS
ALREADY GRADED A+ 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
1
, 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
