Alkanes Flashcards
(5 cards)
1
Q
General formula of alkanes
A
CnH2n+2
2
Q
How do longer carbon chains affect the boiling point of alkanes
A
They increase the boiling point - Longer chains means the stronger the London forces.
This is because there is more surface contact and more electrons to interact
This means it takes more energy to overcome the stronger London forces
3
Q
General formula of cycloalkanes
A
CnH2n
4
Q
How do branched chain alkanes have an affect on the boiling point compared to straight chain alkanes
A
Branched chains have lower boiling point
This is because they cant closely pack together so there is less surface contact
5
Q
Why does free radical substitution produce a mixture of organic products
A
- Further substitution where it produces more termination products
- Substitution at different positions on the chain
