CP 04 - Rate of hydrolysis of halogenoalkanes Flashcards
(8 cards)
What is a hydrolysis reaction?
Hydrolysis is a type of reaction where water is involved.
How do you test the rate of hydrolysis of different haloalkanes?
You can test the rate of hydrolysis of chloro-, bromo-, and iodo- haloalkanes.
What are the expected results of these hydrolysis reactions?
The expected results vary based on the type of haloalkane.
Why are water baths used?
To keep the temperature constant so it doesn’t interfere with the rate of reaction.
What is uncertainty?
The uncertainty in a measurement is the interval within which the true actual value is expected to lie.
What is percentage uncertainty and how do you calculate it?
Percentage uncertainty in a measurement is calculated as (uncertainty / measured value) x 100.
How can you decrease the uncertainty in measurements?
Use a lower temperature to reduce the rate of reaction, making the time taken longer and thus decreasing percentage uncertainty.
What kind of reaction is the hydrolysis of haloalkanes?
It is a nucleophilic substitution reaction.
