2025, CHEM 219 PORTAGE LEARNING - MODULE 1 EXAM|
COMPLETE EXAM QUESTIONS AND CORRECT ANSWERS| (2025
UPDATE) ASSURED SUCCESS
1. What is organic chemistry?: Branch of chemistry that studies the structure, properties,
composition, reaction and synthesis of organic compounds which contain carbon atoms.
2. Catenation: Ability of ab element to form bonds with itself, resulting in formation of chains, rings
or complex structures.
Allows for vats diversity of organic compounds in terms of reactivity and properties
3. The properties & reactivity of an organic molecule are controlled by its:
com-position & shape
4. Why do atoms form bonds to other atoms?: Energetic stability
5. To say an atom is energetically stable means that the overall energy of
the atom is: lower when in the bonded state than in a non bonded state
6. T/F
Lower energy typically means greater stability? Why: True
b/c the electron configuration of the atom - atomic valence
7. Valence: # of bonds an atom will form to fill its valve (outermost) shell.
The atom achieves stability from a full valence shell, as there is no desire to make bonds
8. Knowing the valence of an atom is important because it indicates ...: How
many bonds a given atom will typically form when it combines with other elements to make a
molecule
