Organic Chemistry Exam 2
According to the energy diagram of Newman projections, a rotation of __________ degrees has the highest energy.
According to the energy diagram of Newman projections, a rotation of __________ & __________ degrees has the lowest energy.
0 and 360
Lower energy = __________ stable
Higher energy = __________ stable
Lower energy = More stable
Higher energy = Less stable
What are two factors that effect the relative stability of Newman projections?
What is sterics?
Sterics is when two methyls run into each other because the atoms take up the same space
What is tortional strain?
Tortional strain is when two bonds are close together in eclipsed conformers.
Which is more stable eclipsed or staggered?
These are __________ reactions
The arrow points towards one carbon in the double bond and away from the other. What happens to the carbon it points towards?
It receives the new bond
The arrow points towards one carbon in the double bond and away from the other. What happens to the carbon it points away from?
It becomes the carbocation
Which reaction is correct and why?
A because it is secondary and B is primary
What is the inductive effect?
The more carbon-substituted carbon will become the carbocation because it is more stable.
Are alkane and cycloalkanes polar or nonpolar?
How do alkanes and cycloalkanes interact?
By dispersion factors
Alkanes and cycloalkanes are __________ dense than water.
(they float on water)
What is the Cahn-Ingdid-Prelog?
a method of prioritizing substituents based on the atomic numbers of the atoms directly attached to the double bonded carbons.
Put these in order from highest to lowest priority:
Which has the highest priority
C-C or C=C
