How does bond enthalpy influence the rate of reaction? Flashcards
1
Q
The rate of substitution of different halogenoalkanes will vary. When substitution occurs, the carbon-halogen bond (C-X) is broken and the lower the bond enthalpy of the C-X bond, the more likely the halogenoalkane will undergo
A
substitution
2
Q
The C-…. bond is the strongest bond as it requires the most energy so will …
A
F
to break, therefore fluoroalkanes will have the slowest rate of reaction.
3
Q
The C-.. bond is the weakest bond as it requires the least amount of energy to break, therefore…
A
I
iodoalkanes will have the quickest rate of reaction.
