CHEM 103 EXAM 4 QUESTIONS AND
ANSWERS WITH CORRECT
SOLUTIONS 100% CORRECT RATED
A+
Question: What occurs during a standard "Addition Reaction" in organic
chemistry?
Answer: ✔️✔️ In an addition reaction, the components of a molecule are added
across a pi bond (such as a double or triple bond), resulting in the conversion of
unsaturated bonds into saturated ones.
Question: How is the process of "Hydrolysis" defined?
Answer: ✔️✔️ Hydrolysis is a chemical breakdown process where a larger
molecule is split into smaller parts through the chemical addition of water.
Question: What characterizes a "Substitution Reaction"?
Answer: ✔️✔️ This reaction involves the replacement of an atom or a
functional group within a molecule with a different atom or group of atoms,
while the overall saturation of the molecule typically remains unchanged.
Question: What specifically happens during a "Hydration Reaction"?
Answer: ✔️✔️ A hydration reaction is a specific type of addition where water
($H_2O$) is added across the double bond of an alkene, typically resulting in
the formation of an alcohol.
Question: What is the mechanism behind a "Condensation" reaction?
Answer: ✔️✔️ This occurs when two molecules combine to form a single
larger molecule, simultaneously losing a small byproduct, which is most
commonly a water molecule.
, Question: How can you distinguish between "Oxidation" and "Reduction" in
organic systems?
Answer: ✔️✔️ These processes are defined by the change in bond composition:
Oxidation: Involves the addition of oxygen or the removal of hydrogen
atoms.
Reduction: Involves the addition of hydrogen or the removal of oxygen
atoms.
Markonikov's Rule -ANSWER ✔️✔️hydrogen atom from water will add to the
carbon that originally had more hydrogen atoms
alpha particle -ANSWER ✔️✔️
Beta particle -ANSWER ✔️✔️
Gamma Ray -ANSWER ✔️✔️
positron -ANSWER ✔️✔️
half life -ANSWER ✔️✔️time required for one half of nuclei in a sample of
radioactive material to decay
radioactive dating -ANSWER ✔️✔️process by which approximate age of an
object is determined through the use of certain radioactive nuclides
-can measure age of organic material
-effective until about 50000 years
