What is the focus of organic chemistry in this material?
Chemical
reactivity of
hydrocarbons
View source
Why is hydrocarbon chain structure important in human health?
It affects
cholesterol
levels and health
View source
What is the chemical reactivity of alkenes?
They undergo
addition reactions
View source
How do you determine the product from an addition reaction of alkenes?
By analysing the reactants and
conditions
View source
What is the stability of carbocations?
Tertiary
carbocations are
more
stable
View source
What is cholesterol associated with?
HDL
and
LDL
levels
View source
What does HDL stand for?
High-density lipoprotein
View source
What does LDL stand for?
Low-density lipoprotein
View source
How does LDL affect blood vessels?
It
deposits
in vessels,
narrowing
passageways
View source
What is β-sitosterol believed to do?
Help
lower
levels of
LDL
cholesterol
View source
What type of bond is the C-H bond in alkanes?
Non-polar
bond
View source
Why are alkanes considered unreactive?
They do not react with
electron pairs
or
charges
View source
What type of reactions do alkanes undergo?
Radical
reactions
View source
What happens during the chlorination of methane?
Free radicals
react to form
methyl radicals
View source
Why are free radicals very reactive?
They have a
single
unstable
electron
View source
What is produced when a methyl radical attacks a chlorine molecule?
A
chlorine radical
is produced
View source
What can UV light produce in your skin?
Radical species
View source
What do alkenes contain?
A C=C
double
bond
View source
What is the effect of hydrogenation on fats?
It leads to
trans-double bonds
View source
What are trans-fats similar to in their effects?
Saturated fats
on
cholesterol levels
View source
What is the difference between cis and trans isomers?
Cis has
substituents
on the
same
side
View source
What is the Z-isomer needed for?
For
tamoxifen
as an
estrogen receptor antagonist
View source
When do we use E and Z naming systems?
When
substituents
on
C1
and
C2
differ
View source
How do you determine priority in E/Z designation?
By
ranking
atoms connected at
comparison point
View source
What is the stability comparison of cis and trans alkenes?
Cis alkenes are
less stable
than trans
View source
What is the nature of the C=C bond in alkenes?
It is
electron-rich
and
nucleophilic
View source
What happens during the addition reaction of alkenes?
The alkene
attacks
an
electrophile
View source
What is formed when a carbocation is created?
It is
electrophilic
with a
positive
charge
View source
What can be added to alkenes during reactions?
Halogens
or
water
with
acid
catalyst
View source
What occurs during addition to unsymmetrical alkenes?
More
stable
carbocation
is formed
View source
What is the summary of alkanes and alkenes?
Alkanes are
unreactive
; alkenes undergo
addition
View source
What is the order of carbocation stability?
Tertiary
>
secondary
>
primary
View source
How is the product of an addition reaction predicted?
From the
stability
of the
carbocation
formed
