Question 3 Not yet graded / 0 pts
Describe the fundamental structural differences between alkanes,
alkenes, and alkynes.
Your Answer:
Alkanes have a c-c bond
Alkenes have a minimum of one C=C bond
Alkynes have a minimum of one
Answer:
AlkANES have only C-C single bonds (saturated).
AlkENES have at least one C=C.
AlkYNES have at least one C≡C.

Your Answer:
, Module 2 Problem Set: Principles of Organic Chemistry with Lab
Two different Newman projections of a linear alkane molecule are shown
below. Answer the questions which follow.
i) What is the IUPAC name of the molecule shown?
ii) Label each projectionsta
asggeredor eclipsed.
iii) What term describes the relationship between these two
conformations?
iv) Which of the two conformations would be more stable? Explain.
Question 6 Not yet graded / 0 pts
Your Answer:
Arrange the following molecules in order of increasing boiling point.
1. butane
Provide a brief explanation for the order that you chose.
2. staggered
3. eclipsed
4. These two conformations are bonded
5. a) is more stable
Answer
i) Butane
ii) A =staggered, B =eclipsed
iii) Rotamers
iv) A would be more stable, as a staggered conformation
removes some repulsion that occurs when the electrons in the
bonding orbitals are aligned directly on top of one another
(eclipsed
).
