Alkenes/Alkanes Flashcards
What is Markowniff’s rule and why does it occur
Hydrogen gets attached to the carbon with most hydrogen attached to it –> most stable carbocation intermediate
When does a E and Z isomer occur
When Each C atom of the double bond is attached to 2 different groups of atoms
what is the defenition of homologous series
series of orgnaic compound having the same functional group but with each successive member different by ch2
what is the catalysts required when you and turning an alkene into an alkane via H2
Nickel catalyst
What is the reagent and conditions for adding water to an alkene to make an alcohol
Steam(reagent) and acid catalyst
What is an advantage and disadvantage of isomg combustion as a dispoasl method for waste polymers
Advantage: Energy Production
Disadvantage: Formation of HCl`
What is the defenition of electrophile
Electron pair acceptor
What are 3 ways that waste polymers can be processed in a sustainable way
Combustion
Recycling
Used as Organic Feedstock
How do you converted Alkene into Alkane
Add H2 reagent and nickel catalyst
What is a difference between a pi and sigma bond
Sigma bond is between bonding atoms and pi bonds exist above and below bonding atoms
Why do some compounds not have E/Z Isomers?
One carbon atom is attached to two groups which are the same
What is PTFE
PolyTetraFluoroEthene
What is meant by the term structural isomeres
Having same molecular formula but different structural formula
What does curly arrows represent in a curly arrow diagram
Movement of a pair of electrons
What are 2 advantages of polymers made from natural foods
They are Biodegradable and they do not produce toxic gases on combustion
How does a pi bond occur
When a p orbital from each Carbon overlap sideways
What are aromatic aliphatic and alicyclic isomers
Aromatic isomers what circles in shapes
Aliphatic iis when a shape is CONNECTED
Alicyclic is shapes but without any shape in the middle
What are the steps for bond fission
Initation - When CL2 is broken apart by UV Light and they contain a free electron(radical)
Propogation - When Cl radical attacks CH3 and becomes HCL with CH3 radical and then CH3 attacks CL2 and becomes CH3CL with CL radical forming
termiantion when they all make up
Suggest ways to reduce enviornmental damage in terms of polymeres
Develop Biodegradable Polymers
Develop ways of sorting and recycling Polymers
How would you define a steroismer
2 or more compounds with the same strucre but different arrangements in space
Why does BP decrease with more branching
More branching means less surface contact which means weaker LDF hence LDF requires less energy to overcome
What is an example of homolytic fission
One electron from the bond goes to each chlorine
