Well im doing this experiment..

and looking at the rate of hydrolysis of halogenoalkanes

And i needed help with the factors, ive looked at a few sites but there no help.

I was doing:

C4H9 - X  ------> C4H9OH + X-

I will be adding 2 drops of (In each seperate test tube) :ChloroButane, IodoButane, BromoButane.  In a test tube with 1CM3 of Ethanol.

The factors are:

Electronegativity Which is fairly easy but i really need help on:

Bond Enthalpy of C-Cl, C-Br, C-I.

Stablity of carboctaion

Solution - Polar solvents

Hyperconjugation

Induction

and SN1 Vs SN2.

If you could help i would be very grateful, im really stuck :'(

Can you have hdyrolysis if you don't have any water?

Yeah.

Dw i managed to do all that stuff.

For my prediction i wrote that i believe bond enthalpy >>>>>> Other factors, and rate of reaction depended on how quickly yhe bond was broken..

Im having difficulty backing this up with scientific knowledge, any idea/tips.




Also if there is a large difference in electronegativity, does that mean the bond enthalpy will be greater, and just to make sure it would be a reactive compound.
