Alkanes And Structural Isomerism Flashcards
1
Q
What is a sigma bond?
A
Head on overlap of two atomic orbitals directly in line between the two bonded atoms
2
Q
Structural isomer definition
A
A structural isomer has the same molecular formula but a different structural formula
3
Q
What reactions do alkanes participate in ?
A
Combustion and radical substitution
4
Q
What are the steps in the radical substitution mechanism
A
- Initiation - formation of the radicals
- Propagation - two steps to create the products and regenerate the radical
- Termination - three possible combinations of the radicals
5
Q
Homolytic fission definition
A
The breaking of a covalent bond with one of the bonded electrons going to each electron, forming two radicals
