problems. This is especially important in subjects like proof-based mathematics.Calculation and Accuracy: Mathematical exams test a student’s ability to perform accurate calculations and apply
mathematical principles in the correct sequence to reach a solution.Understanding of Concepts: Beyond solving problems, mathematics exams test students’ conceptual understanding of core topics,
such as algebra, geometry, calc
Have one or more carbon-carbon double (pi) bonds. Also called olefins. -
Answer Alkene
What is the degree of unsaturation of an alkene? - Answer One
T or F: Alkenes are less reactive than alkanes. - Answer False
Conformers that have the same groups but different geometry on
stereogenic centers. - Answer Diastereomers
What is an example of a diastereomer? - Answer Cis & Trans
What is the Cann-Ingoid-Prelog Naming System? - Answer Rule 1: Highest
atomic number is the highest priority (If atomic number is the same, use
atomic mass)
Rule 2: If the atomic number and mass are the same, use the next attached
atoms until the first difference is observed.

When the highest priority groups are both on the top or bottom of the
molecule. - Answer (Z)-
When the highest priority groups are on opposite sides of the molecule. -
Answer (E)-
Is the (E) or (Z) naming used when the groups on one side of the molecule are
, the same? - Answer No

T or F: Conformers have the same E/Z name while constitutional isomers may
or may not. - Answer True
What is the difference between a cis and trans alkene? - Answer
T or F: A cis alkene is less stable than a trans alkene because there is more
steric repulsion in a cis alkene. - Answer True
Are (E) or (Z) alkenes more stable? Why? - Answer (E) alkenes
because they have less steric repulsion
Have the same group on the same side of the molecule. Have the same relative
stability as their (Z) constitutional isomers. - Answer Geminal
Alkenes with two substituent groups on them. - Answer Disubstituted
Alkenes
What is the relative substituent stability for alkenes? - Answer
T or F: An alkene with more Csp^2-Csp^3 bonds is more stable. -
Answer True
Why are Csp^2-Csp^3 bonds more stable and stronger than Csp^3-Csp^3
bonds? - Answer They have more s character in their orbitals, which
corresponds to lower energy electrons
Reactions where the pi bond is broken, the X-Y bond is broken, and a new C-
