describe the dehydration of ethanol to ethylene and identify the need for a catalyst in this process and the catalyst used
The reaction requires a catalyst as the water molecule itself will not attack the electrons in the ethene double bond.
Is that enough?
They're both as bad. If you play sport you get tired, and if you sit around you get bored. My advice is, don't bother studying until the last two week. ;)
Yes, that is true, they assume you get 100 for 2U. But thing is, you don't get a band because you don't sit for the exam, nor do you do the assessment tasks....well not for my school anyway.
